Futter Get started For Beginner

Sure, I can help you install Flutter on your machine! Here are the steps you need to follow:

Step 1: Install the Flutter SDK

  1. Go to the Flutter website https://flutter.dev/docs/get-started/install and download the latest stable release of the Flutter SDK for your operating system (macOS, Windows or Linux).
  2. Extract the zip file to a suitable location on your machine. For example, on macOS, you might extract the zip file to /Users/your-username/flutter.
  3. Add the Flutter SDK to your PATH environment variable by opening your terminal and running the following command:
    export PATH="$PATH:[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter/bin"

    Note: You’ll need to replace [PATH_TO_FLUTTER_GIT_DIRECTORY] with the actual path where you extracted the Flutter SDK.

    To make the change to your PATH variable permanent, you can add the above command to your shell configuration file (e.g., .bashrc or .bash_profile on macOS).

  4. Verify that Flutter is installed correctly by running the following command:
    flutter doctor​

    This command will check your environment and display a report of the status of your Flutter installation. If everything is set up correctly, you should see a message that says “All Flutter SDK checks passed!”.

Step 2: Install an IDE

You can write Flutter apps using any text editor, but for a more complete development environment, you may want to use an IDE (Integrated Development Environment). There are several popular IDEs that support Flutter development, including Android Studio, Visual Studio Code, and IntelliJ IDEA.

For this tutorial, we’ll use Visual Studio Code, which is a free and lightweight IDE that has great support for Flutter development.

  1. Go to the Visual Studio Code website https://code.visualstudio.com/ and download the latest stable release of the IDE for your operating system.
  2. Install the IDE by following the prompts in the installer.

Step 3: Install the Flutter and Dart extensions in Visual Studio Code

  1. Open Visual Studio Code.
  2. In the left-hand sidebar, click on the Extensions icon (it looks like four squares arranged in a grid).
  3. Search for “Flutter” in the Extensions Marketplace and install the Flutter extension.
  4. Search for “Dart” in the Extensions Marketplace and install the Dart extension.

Step 4: Create a new Flutter project

  1. Open Visual Studio Code.
  2. Click on the “View” menu and select “Command Palette”.
  3. In the Command Palette, type “Flutter: New Project” and press Enter.
  4. Choose a location to create your new Flutter project and give it a name.
  5. Wait for Visual Studio Code to create the project.

Step 5: Run your Flutter app

  1. Open the main.dart file in your project (it should be in the “lib” directory).
  2. If you see a message that says “No device available”, connect your mobile device to your computer or launch an emulator.
  3. Click on the “Run” menu and select “Run Without Debugging” or press F5.
  4. Wait for the app to build and launch on your device or emulator.

Congratulations! You have successfully installed Flutter and created a new Flutter project. You’re now ready to start building Flutter apps!
