    Steps to Getting Started with Flutter App Development and Its Benefits

    April 27, 2023 — By Brain Technosys

    Recently Flutter has gained significant attention as it is a software development framework. Beyond this, it has gained popularity among developers as well. Flutter is developed by Google, and is recognized as an open-source platform, which can help any developer to create high-performance based applications, meant for mobile devices. The applications are meant to be used for iOS as well as Android gadgets. Dart programming language is used in Flutter as it provides a wide range of pre-built widgets, tools, and libraries that can make the process of development easier and faster. The advantages of this Flutter development is numerous, thus, making it as an ideal choice for developers who plan to build mobile applications for their businesses. The following are some of the advantages of using Flutter for mobile app development. They include:

    Development Is Faster

    In comparison to traditional methods, developers will be able to build applications faster while using the Flutter development process. This is considered as the most significant advantage of Flutter. Creation of user interfaces quickly is the special feature of Flutter development as it comes with a wide range of pre-built widgets. Besides, Flutter’s ‘hot reload’ feature enables developers to make changes to the code and find the results, immediately. This significantly speeds up the process of development several times.

    Compatibility Cross-Platform

    Using the same code base, Flutter being a cross-platform framework, enables developers to create applications for iOS as well as Android gadgets. This strategy helps the builders to build mobile applications that can operate on both the operating systems, flawlessly. This not only reduces the time but also the resources needed to develop separate applications for each platform.

    User Interfaces Are Beautiful

    With a range of customizable widgets and tools, Flutter enables developers to create initiative user based interfaces, and they are beautiful. Material Design widgets of Flutter provide a range of pre-designed user interface elements, which can easily be customized to fit the look and feel of the brand.

    High Performance Characteristics

    Delivering high-performance mobile applications is accomplished through Flutter design. The reactive programming model of Flutter ensures the applications exhibiting are highly responsive and performant. Besides, the ahead-of time compilation feature of Flutter helps applications to start up quickly, and run smoothly even on lower-end devices.

    Integration Easy

    Integration with other technologies and platforms is possible using Flutter. With Firebase, it integrates seamlessly, which is a cloud based platform, offering a range of tools and services for building mobile applications. Besides, with native code, Flutter can be integrated helping developers to use the existing code and libraries in their applications.

    How to get started with Flutter?

    The following are the steps used to enable any individual to understand the basics of Flutter development, and running up with Flutter project.

    Step 1: Setting up of development environment

    Prior to starting the process of building Flutter apps, setting up of a development environment is essential. Accordingly, as a first step, it is necessary to download and install the Flutter SDK from its official Flutter website. Thereafter, installation of an integrated development environment (IDE), like Visual Studio Code, IntelliJ IDEA, and Android Studio is done. This is followed by configuring IDE to work with Flutter, which is started. This procedure involves installation of Dart and Flutter plugins, and setting up of environment related to IDE’s PATH that is a variable. This process includes setting up of Flutter SDK’s bin directory parameters.

    Step 2: Creating the first Flutter project

    In this step, after setting up of the development environment is over, creation of the first Flutter project is done through the execution of certain commands in the terminal. This process will create a new Flutter project directory, named my app. This directory can be opened in the IDE, which is followed by building the app.

    Step 3: Flutter architecture and Its Understanding

    In this step, Flutter makes use of a reactive programming model wherein the app state changes. Further, the user interface (UI) gets updated automatically to reveal these changes. Accordingly, Flutter achieves through the usage of a widget tree wherein each widget represents a part of the UI. However, Flutter rebuilds the widget and its child widgets when the state of widget changes. Further, Flutter makes use of a layered architecture, which separates the presentation layer consisting of widgets from the business logic layer or Dart code. Hence, developers will be able to build reusable and maintainable code, accordingly.

    Step 4: Building up of the first Flutter app

    In this step, it is now the time for building the first Flutter App. Accordingly, Flutter offers a rich set of widgets that are customizable readily, which can be used to generate a beautiful and responsive user interface.

    Step 5: Debugging and Testing of Flutter app

    In this step, the process of testing and debugging covering important elements in the development process is done. For this process, Flutter offers several tools that can be used to test and debug the app. They include, Flutter DevTools, which is nothing but a suite of debugging and performance tools. This can be accessed from the IDE or using command line.


    Being a flexible as well as a powerful framework, it allows the developers to build high quality, mobile applications that are natively compiled, meant for multiple platforms using a single codebase.
