    Introduction to Flutter

    Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for MOBILE, WEB, and DESKTOP from a single codebase. It is very easy to learn and currently it is getting more and more popular. With this blog post, you will learn some basic stuff about Flutter and after reading it, you will be able to create a simple application using this technology.

    Click here to check out more details about flutter.

    Tools & Setup


    • Flutter & Dart SDK
    • Anyone IDE Android Studio (Recommended), Visual Studio Code or IntelliJ IDEA
    • To edit this project you must have Flutter and Dart installed and configured successfully on your computer.
    • Set up your editor - Install the Flutter and Dart plugins.
    • If you have got Android SDK installed and configured, to install Flutter you only need to:
      • Download Flutter SDK from official website and extract it.
      • Add path to previously extracted SDK to your PATH variable
      • Run flutter doctor tool to check if everything is configured correctly.
      • All above steps are mentioned here:

    Android Studio – Windows​

    Step 1 : Get the Flutter SDK

    1 Download the following installation bundle to get the latest stable release of the Flutter SDK:

    2 Extract the zip file and place the contained flutter in the desired installation location for the Flutter SDK (for example, C:\src\flutter; do not install Flutter in a directory like C:\Program Files\ that requires elevated privileges).

    Step 2 : Update your path

    If you wish to run Flutter commands in the regular Windows console, take these steps to add Flutter to the PATH environment variable: From the Start search bar, enter ‘env’ and select Edit environment variables for your account. Under User variables check if there is an entry called Path:


    Note that you have to close and reopen any existing console windows for these changes to take effect.

    You are now ready to run Flutter commands in the Flutter Console!

    Step 3 : Run flutter doctor

    From a console window that has the Flutter directory in the path (see above), run the following command to see if there are any platform dependencies you need to complete the setup:

    c:\src\flutter>flutter doctor

    If you find any issue during environment setup, please go online Click here

    Android Studio – macOS​

    Step 1 : Get the Flutter SDK

    Step 2 : Update your path


    Path variable needs to be updated to access “flutter” command from terminal. you can just update path variable for current terminal window only. and if you want to access flutter commands from anywhere in terminal, we need to update SDK path permanently.

    To update PATH variable, we need to open terminal.

    To update PATH variable for current terminal window only, then enter this command "export PATH="$PATH:`pwd`/flutter/bin"" and hit enter key.

    To update PATH variable permanently, then Open or create .bash_profile file. to open or create that file, then enter "sudo open -e $HOME/.bash_profile" and hit enter key.

    Append below line to bash_profile file at bottom of all other content. "export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin"" as [PATH_TO_FLUTTER_GIT_DIRECTORY] is actual path of SDK folder.

    Run this command on terminal "source $HOME/.bash_profile" to refresh PATH variables.

    Then check whether our SDK is successfully installed or not.

    You are now ready to run Flutter commands in the Flutter Console!

    Run "flutter doctor" into terminal, If you are getting check list of flutter sdk requirements, it means SDK is successfully installed on your machine. and you can start building flutter apps on your machine.

    If you find any issue during environment setup in macos, please go online Click here

    Android Studio – Linux​​

    Step 1 : Get the Flutter SDK

    Step 2 : Update your path


    Path variable needs to be updated to access “flutter” command from terminal. you can just update path variable for current terminal window only. and if you want to access flutter commands from anywhere in terminal, we need to update SDK path permanently.

    You’ll probably want to update this variable permanently, so you can run flutter commands in any terminal session. To update PATH variable, we need to open terminal.

    export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin"

    1. Run source $HOME/. to refresh the current window, or open a new terminal window to automatically source the file.
    2. Verify that the flutter/bin directory is now in your PATH by running:

    echo $PATH

    Verify that the flutter command is available by running:

    which flutter

    You are now ready to run Flutter commands in the Flutter Console!

    Getting Started (Build & Run)


    All below steps are must be followed to build and run application

    Download Project

    Download and find the your project folder, use your preferred IDE (Android Studio / Visual Studio Code / IntelliJ IDEA) to run the project.


    Get Dependencies

    After you loaded project successfully, run the following command in the terminal to install all the dependencies listed in the pubspec.yaml file in the project's root directory or just click on Pub get in pubspec.yaml file if you don't want to use command.

    flutter pub get


    All below steps are must be followed to build and run application


    Build and Run App

    1. Locate the main Android Studio toolbar.
    2. In the target selector, select an Android device for running the app. If none are listed as available, select Tools > Android > AVD Manager and create one there. For details, see Managing AVDs.
    3. Click the run icon in the toolbar, or invoke the menu item Run > Run.

    After the app build completes, you’ll see the app on your device.

    If you don’t use Android Studio or IntelliJ you can use the command line to run your application using the following command


    Below step requires flutter path to be set in your Environment variables. See

    flutter run

    You will see below like screen after you have build your app successfully


    Try hot reload

    Flutter offers a fast development cycle with Stateful Hot Reload, the ability to reload the code of a live running app without restarting or losing app state. Make a change to app source, tell your IDE or command-line tool that you want to hot reload, and see the change in your simulator, emulator, or device.


    Do not stop your app. let your app run.
