Introduction

This tutorial provides a step-by-step guide to installing Dart, a programming language optimized for building mobile, desktop, and web applications. Whether you're a beginner or an experienced developer, following these steps will help you set up Dart on your system effectively.

Step 1: Download Dart SDK

• Visit the official Dart website at dart.dev.
• Choose the appropriate installation method based on your operating system:
  • Windows: Download the Dart SDK installer.
  • macOS: You can install Dart using Homebrew with the command:

    brew tap dart-lang/dart
    brew install dart
    

  • Linux: Follow the instructions for your specific distribution. For example, on Ubuntu, you can use:

    sudo apt update -y
    sudo apt install apt-transport-https
    sudo sh -c 'wget -qO- https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'
    sudo sh -c 'wget -qO- https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list > /etc/apt/sources.list.d/dart_stable.list'
    sudo apt update -y
    sudo apt install dart
    

Step 2: Set Up Your Environment

• Windows:

  • After installation, add Dart to your system PATH:
    • Right-click on 'This PC' and select 'Properties'.
    • Click on 'Advanced system settings' and then 'Environment Variables'.
    • Under 'System variables', find Path and click 'Edit'.
    • Add the Dart SDK path (usually C:\dart\dart-sdk\bin).

• macOS and Linux:

  • You may need to configure your terminal profile to include Dart in your PATH. Add the following line to your .bashrc or .zshrc file:

    export PATH="$PATH:/usr/lib/dart/bin"
    

  • Refresh your terminal by running:

    source ~/.bashrc
    

    or

    source ~/.zshrc
    

Step 3: Verify the Installation

• Open a command prompt or terminal window.
• Type the following command to check if Dart is installed correctly:

  dart --version
  

• You should see the version number of Dart displayed. If you encounter an error, revisit the previous steps to ensure the installation and PATH configuration were done correctly.

Step 4: Install Dart Packages

• To manage packages in Dart, you will use the pub tool.
• Create a new Dart project by running:

  dart create my_project
  

• Navigate to your project directory:

  cd my_project
  

• To add packages, modify the pubspec.yaml file in your project and include the desired dependencies. For example:

  dependencies:
    http: ^0.13.3
  

• Install the packages by running:

  dart pub get
  

Conclusion

You've successfully installed Dart on your system and set up your environment for development. You can now start building applications using Dart. As a next step, consider exploring Dart's features or starting a sample project to familiarize yourself with the language. Happy coding!
