Roadmap to Flutter Development

What is Flutter?

It is an open-source mobile SDK (Software Development Kit) which helps in developing applications for iOS, Android, Web, Desktop using a single codebase. Development of applications using Flutter will be a bit faster and easy.  

Also, using one time code, you can make beautiful applications in varied technologies such as iOS,  Android, etc. 

Why Flutter?

  • Fast development experience 
  • Heavily optimized 
  • Rich set of widgets 
  • Reduces cost and complexity of app production across platforms 
  • Single codebase to rule them all 
  • Simple and easy to learn and use 
  • Hot Reload/ Hot Restart feature makes it very easy to design 

Tech stack required for Flutter:

C | C++ | DART | SKIA (2-D RENDERING ENGINE) 

Note: In order to design a UI very quickly, you can learn how to use Flutter Flow.

Roadmap:

Step 1 : Know a programming language and OOPS concept

Before proceeding with development, try to go through the OOPS Concept first. Brush up the concepts once and then start with a programming language.  

Flutter actually uses DART, so try to be thorough with it. Be clear with the basic dart concepts. 

Step 2 : Understand the IDE

Get an idea of how the IDE works. Go through the interface, get an overview of the shortcut commands as  well. 

Step 3 : Start off with the very basic concepts

Get along with the variety of widgets such as Stateful and Stateless, Accessibility, Async, Cupertino, Containers, Rows, Columns, Scaffold. Other concepts will include Lists, Map, Lambda function, Aspect Ratio, Alignment, Cards, Sized Box. Understand about the Styles and Assets as well. 

Step 4 : Try static UI then

Try creating a static UI first. Make use of text, image, button, raised buttons, containers, rows, columns,  constrained box, elevated button, etc.

Step 5 : Start with Dynamic UI

Continue with creating dynamic UI after you understand how to create a static UI. Concepts include List View, Grid View, Expanded class, Slivers. 

Step 6 : Know the animations 

The animations are a very important aspect of UI such as Curved Animation, Animation Controller, Tween, Animated Widgets, Animated Builder, Implicit animations, Hero animations. 

Step 7 : Know about memory and storage management 

Learn about the File System, Shared Preferences, how states actually work, SQLite. 

Step 8 : Know 3rd party libraries and state management

There are multiple third party libraries that one should know about such as font_awesome, http, dio, get_it, cached_network_image, SQFLite, RxDart, bloc_pattern, flutter_webview_plugin. The State Management includes Provider, setState, BLoC, Redux, etc. 

Step 9 : Understand the version control 

Version Control is basically for tracking and managing changes to the software code. Through this, a developer will be able to trace out the changes that have been done to the code. 

So for this, get familiar with any one of these – Git, Github, bitbucket, GitLab.  

Also, if possible try to get your hands on any one of these using Terminal or Source Tree. Though Source Tree is easy to use, one should know Terminal commands as well.

Step 10 : Try to work with Native Integration

After learning Flutter, try once with native integration so that one can get an idea like how the actual android, iOS, desktop apps work and how they will be uploaded on their respective platforms such as App Store and Play Store. 

For this, you can go through different programming languages such as Java, Kotlin, Swift, Objective C, and different IDE’s such as Xcode, Android Studio. 

Also, get an idea of iOS Profiles, Certifications, App Signing. 

Apart from these, Learn Project Structures as well. There are certain predefined architectures such as MVVM, MVC, MVP, etc. 

Note: This roadmap has been created keeping in mind a person who is learning from scratch. If you find another roadmap easier to follow, don’t hesitate from trying that out!

 

Flutter Vs React Native for developing cross platform applications

Mobile applications are becoming a phenomenal success in the modern world and therefore, many IT organizations are working on developing highly-efficient mobile apps. 

With over 3.6 million mobile users globally, the mobile app development demands innovative solutions that are time-efficient and require less effort. In 2022, there will be two fundamental hybrid frameworks for app development frameworks – Google’s Flutter and Meta’s React Native. 

And both these frameworks are enjoying a high wave of popularity. Given the incredible supportive features of these two frameworks, one question keeps floating in the app development realm: which one is the best framework for mobile app development – Flutter or React Native? 

This blog aims to give more clarity to developers about which framework is the best suited for mobile app development. 

Without any further ado! Let’s get started!

What Is Flutter Framework?

Google’s official brainchild, Flutter, is a cross-platform UI toolkit for developing robust, beautiful, native-complied applications. This platform can power various platforms web, desktop, and mobile applications. 

Launched in May 2017, the popularity of the Flutter framework has grown immensely over the years. One of the most attractive features of Flutter is that it allows cross-platform application development using a single codebase. With a conventional app development ecosystem, a company would need several tools and an intricate team of developers to create an application that would run on the web, mobile, and desktop.

For example, with traditional, you might require:

  • A developer with web development expertise using React to develop the website
  • Another developer developing a desktop version using C# and Java 
  • For mobile applications (iOS and Android) development, a dedicated mobile developer utilizing native frameworks such as Kotlin and Swift 
  • This traditional approach would require a complex collaboration between a team of expert app engineers and surely a ton of meetings to ensure consistency is maintained across all platforms. 
  • And you can’t skip the elaborate testing and addressing bugs individually for each platform. 

Flutter eliminates all these complexities. Companies can easily hire one qualified Flutter developer to develop apps across multiple platforms with just a single codebase to manage. 

While Flutter offers several benefits, time and resource efficiency for launching and maintaining an application remains the shining star. 

Now that we know what Flutter framework is, let’s focus on an interesting fact about the framework:

  • Almost 2 mil developers trust and use Flutter for cross-platform app development. 500,000 developers use it monthly! 

When to Use Flutter?

Flutter can be extremely beneficial in the following situations:

  • Small budget projects
  • Applications with short development and quick delivery timeline
  • Creating UI-centered apps
  • Iteration (Hot Reload)

 Benefits of using Flutter framework for app development

Flutter framework for mobile application development comes with several advantages, including:

  • Flutter is platform-agnostic
  • Flutter simplifies and speeds application development
  • Flutter is simple to grasp and easy to use
  • Flutter scales well
  • Flutter apps offer an excellent user experience

That’s a comprehensive overview of the Flutter framework. Now let’s take a look at React Native. 

What Is React Native?

Meta’s official cross-platform framework, React Native, is supported by a codebase in JavaScript programming language, making it fairly simple to use for cross-platform application development. Therefore, JavaScript developers get a low barrier to entry in the mobile application development realm. 

Web development isn’t a new or unexplored paradigm. It’s a technical development discipline that has existed for many years. Most web engineers have significant experience in using JavaScript for much of their careers. 

However, mobile development is relatively new. In fact, the mobile app development ecosystem has witnessed popularity and growth only over the past few years. Therefore, if developers are already experts in JavaScript, the learning curve for robust mobile app development using Meta’s React Native becomes relatively easy.

Industry leaders such as Xbox Store apps are trusting the React Native platform for their mobile application requirements. Similar to Flutter, React Native enables cross-platform app development using a single codebase.

When Should You Use React Native?

React Native framework can be worthwhile to explore in the following situation:

  • An application requiring flexible and custom design without losing consistency on cross-platform interfaces.
  • When you need both web and mobile applications, React Native allows code sharing between web and mobile interfaces. 
  • When your development team has gained extensive expertise in JavaScript

Benefits of React Native:

Meta’s official app development platform presents a treasure trove of benefits, including:

  • Extensive base packages since it uses the immensely popular JavaScript language
  • Similar to Flutter, a single codebase enables developers to engineer an app for multiple interfaces simultaneously rather than individually.
  • Extends significant developer freedom and flexibility as it allows code reuse and cost-saving
  • An active and vast community supporting the framework 
  • Easy learning curve for React developers

Both React Native and Flutter are cross-platform app development frameworks. So what’s the difference? Let’s find out!

React Native Vs. Flutter

React Native and Flutter are the most preferred app development tools. However, both these frameworks have their own set of advantages and drawbacks. The table below represents the differences between the two platforms.

Parameters Flutter React Native
Parent Company Launched by Google Launched by Meta (formerly Facebook)
Launched on May 2017 June 2015
Backend Programming Language Dart language JavaScript 
Architecture Business Logic Component (BLoC) Flux and Redux architecture. Facebook engineered Flux. Redux is the preference among the React Native community.
User Interface Leverages custom widgets to engineer the application user-interface Leverages native UI controllers to engineer the application user-interface
Documentation Support Presents well-structured and elaborate documentation. Developers can access all required information in one single place. Presents user-friendly but unstructured documentation
Performance Delivers fast-performing applications, and enables application compilation by using the arm C/C++ library making it more aligned to machine code and empowering better native app performance Comparatively, app performance is slow. With React, developers sometimes face certain problems while executing the hybrid application framework.
Testing Presents an ensemble of testing features allowing developers to perform several types of testing including unit, integration, as well as widget testing Leverages third-party application testing tools
Community Support Comparatively less community support since it’s relatively new  Backed by very strong community support providing quick resolution to queries and concerns
Industry Adoption Google Ads

eBay

Hamilton

Alibaba

BMW

Facebook

LinkedIn

Tesla

Instagram

Coinbase

Skype

Learning Curve Comparatively, easier to learn and more developer-friendly. Dart programming language is much simpler to work with and understand compared to JavaScript. Dart also has striking similarities with programming languages used for native mobile app development. JavaScript, on the hand, is far from being a developer-friendly programming language. For developers without experience in working with JavaScript, using React Native can be a challenging task presenting unnecessarily complicated coding. However, it’s an easy task for JavaScript experienced developer to use React Native. 
Debugging Enables easy debugging with tools that support development in both Android Studio and Visual Studio. DevTools and OEM Debugger help developers identify and comprehend errors.
Also supported by Inspector, which allows checking the visual layer of the app and clearly answers why it looks the way it looks
Debugging can be slightly problematic in the React Native framework, especially when a particular exception or error originates in the native part of the application. However, Flipper (debugger) has efficiently addressed the problem of debugging for React Native.

Which One Should You Choose?

The latest research from Statista in 2021 reveals the popularity of both the app development framework. Flutter leads the graph for cross-platform mobile development framework in 2021. The Google brainchild surpassed React Native by 4% (42% for Flutter framework against 38% for React Native).

Still, it’s only fair to say that two frameworks are almost equally popular in the development realm compared to other similar platforms. Both Flutter and React have their benefits and drawbacks. The correct selection should be based on your experience and the individual app development goals and requirements of your project.

If you are already experienced in JavaScript, writing mobile apps codebase in React Native is a simple job. However, if you’re more interested in better performance, enhanced stability, and a more cohesive environment between different ecosystems, Flutter is worth exploring.

 

Flutter developer toolkit: In-demand skills, learning resources, online courses, interview prep, books & more

Google launched Flutter in 2018 as a framework to develop apps for multiple operating systems. In only four years, Flutter has been used by thousands of developers for mobile application development for both Android, iOS, and web platforms. One of the reasons for the popularity of Flutter is its capacity for cost-saving. Instead of building several apps to run on Android, iOS, and web browsers, a single app can be made on the same code base to work on all the platforms.

However, Flutter is relatively new compared to other app development frameworks on the market. This Flutter developer toolkit is created to help developers find all the needed Flutter resources in one place.

Prior knowledge of native programming languages 

Flutter is a framework rather than a programming language. Flutter developers must understand mobile application programming languages such as Java, C#, C++, Swift, and Kotlin. Of all the languages, Kotlin has emerged as a preferred choice for Android development. Google has already made Kotlin the official programming language for the Android platform. Knowledge of Kotlin will help you develop apps faster with Flutter. We have a few toolkits that you can explore to learn about the essential programming languages:

C# developer toolkit

Java developer toolkit

Being familiar with these programming languages will help you quickly take up Flutter and fully utilize its features.

Knowledge of Dart

Dart is the client-based programming language used to write scripts in Flutter. Google has also conditioned it to allow developers to introduce Flutter into cross-platform compatibility applications universally. Dart is a multidimensional programming language for web, mobile, desktop, and server development. Most job openings for Flutter developers ask for knowledge or experience in Dart. Learning this programming language is necessary for landing a job as a Flutter developer.

Experience in SQLite

SQLite is a popular database for multiplatform application development. It stores persisting data much more efficiently than other databases. However, in Flutter, SQLite offers an additional advantage. With the use of the sqflite plugin, SQLite can be easily integrated into Flutter to perform multiple operations such as read, write, update, and insert. Another reason why SQLite is the preferred database for Flutter application is the immense support from the Flutter community and the wide range of information available.

Knowledge of Git

Git is a tool that’s essential for every developer. Irrespective of the framework or programming language, knowledge of Git is mandatory. Flutter developers actively use Git and GitHub to collaborate with other developers. As a version control system, Git provides the capability to keep track of the changes made in the code. Companies expect developers to know Git and its command so that project management can be done quickly.

Learning Flutter

Communication: Listening and communicating are essential for developers. Listening is not just hearing what other teammates or stakeholders say but also anticipating and understanding their viewpoint. Also, your conversations must be concise and unambiguous such that there is no ambiguity to create confusion or anxiety within the team.

Patience: Software development is a complex effort that often includes long processes. Hundreds of intangible tasks must be managed from project kick-off to project development. Learn to be patient with the process and allow yourself enough time to build applications and anticipate the overall requirement so there is less room for error.

Open-mindedness and adaptability: Steven Job’s famous Stanford commencement statement, “Stay hungry. Stay foolish,” has a deep meaning. He implies that open-mindedness in being receptive to other people’s feedback. As a developer, you will have to listen and adapt not only to new ideas but to new technologies, frameworks, and development methodologies.

Why is Flutter better than React Native for developing cross-platform applications?

Cross-platform development has too many advocates now. With so many technologies available, creating platform-independent software with a single code base is possible.

Think about how straightforward it is to deploy and manage a single code for Android and iOS versions of the same app.

The popularity of cross-platform applications is on the rise, contributed by the ease of working on a single codebase, easy availability of hybrid app development tools, and consistent behavior of such applications. 

Another reason to choose the cross-platform approach is that it’s faster and more economical from a business standpoint.

Several frameworks are available for cross-platform development, such as Flutter, React Native, Ionic, Xamarin, and Cordova. However, Flutter and React Native are the market leaders capturing 42% and 38% of the cross-platform development market, respectively.

Both frameworks offer freedom to create the best cross-platform applications, but Flutter still enjoys an edge over React Native.

Why?

That’s what we are exploring in this article.

Flutter and React Native: A background check 

Flutter and React Native was developed as a solution to deploy Android and iOS apps based on a single codebase. Google created Flutter in 2017, while Facebook open-sourced its internal React Native project in 2015.

Flutter is a complete UI framework that allows fast development of user interfaces based on the Material Design and Apple Human interface guidelines. Some popular apps built with Flutter include Google Ads, Alibaba, and Birch Finance.

React Native is Facebook’s cross-platform app development framework based on React (also developed by Facebook). Since 2015, many enterprise-level companies have adopted this framework, including Instagram, SoundCloud Pulse, and Skype.

Let’s find out why developers favor Flutter over React Native.

Performance

Flutter apps are much faster than applications developed with React Native. It has its engine and programming language. Flutter apps are written in Dart; a Java-like programming language optimized explicitly for developing client applications for mobile, web, and server-side platforms. Flutter also has integrated native compilers that convert Dart code to native instructions for ARM processors, resulting in an impressive performance boost.

React Native is entirely based on JavaScript; as a result, the code is more difficult to debug and maintain. Also, in the absence of no native compilers, it’s slower.

Architecture

Flutter is created as a framework for developing UI, which is why it has a low-level Skia engine used in Chrome browsers and Android OS. The engine empowers Flutter to render its component at a higher speed of 60FPS, which results in high performance. Also, it uses its widget library to display Flutter UI seamlessly during UI operation. These architectural features allow Flutter apps to look consistent on Android and iOS. It also results in the unification of the UI appearance regardless of the version of the operating system.

React Native uses a JavaScript engine that acts as a bridge between the native OS components and the JavaScript code of the app. While this approach makes the apps closely resemble native apps, it creates performance issues due to the time taken to interpret JavaScript code.

Smaller app size 

Another benefit of using Flutter for cross-platform application development is the smaller app size. The framework uses fewer additional components to compile the code to simple ARM instructions. Flutter does not store anything more than the bare minimum to run apps. On the contrary, React Native needs more storage to store JavaScript code and interpret the statements. It leads to a bigger app size. For instance, the React Native binary takes up twice as much space on a device’s storage compared to Flutter. As mobile storage is expensive, developers prefer Flutter for cross-platform development.

Development tools and documentation

The convenience of a development tool dramatically depends on the ease of learning and setup. A good framework is easy to learn and operate.

Flutter SDK provides a complete set of tools to help developers quickly learn how to create and debug applications. It also integrates with popular code editors like Visual Studio Code and IntelliJ IDEA. It also offers tools for debugging, test automation, and monitoring app performance. Flutter has a “hot reload” feature that allows developers to run a new code without restarting the whole application. It saves significant time when debugging an application. The Flutter documentation is also top-notch, with some excellent starter toolkit guides to help developers learn fast.

React Native also has a robust documentation and tutorials library supported by its vast developer community. However, it is not beginner friendly, as it can be challenging to set up, and getting started is quite complex if you are new to cross-platform development.

Conclusion 

Although Flutter is relatively new compared to React Native, it is fast becoming the preferred framework for cross-platform development. Development with Flutter is faster, cheaper, and results in high-performance apps – some of the reasons it is better than React Native for cross-platform development.
