Installing and Setting Up the Dart Development Environment

Setting up a Dart development environment is straightforward and can be completed in a few steps. This guide will walk you through the installation process and how to set up your development environment for Dart programming.

Step 1: Download and Install Dart SDK

For Windows

  1. Download the Dart SDK:
  2. Run the Installer:
    • Double-click the downloaded .exe file and follow the installation prompts.
  3. Set Environment Variables:
    • Right-click on This PC or My Computer and select Properties.
    • Click on Advanced system settings.
    • In the System Properties window, click on Environment Variables.
    • Under System Variables, find the Path variable and click Edit.
    • Add the path to the Dart SDK bin folder (e.g., C:\tools\dart-sdk\bin).
  4. Verify Installation:

    • Open Command Prompt and run:

      dart --version
    • You should see the Dart version displayed.

For macOS

  1. Install Homebrew (if you haven't already):

    • Open Terminal and run:

      /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  2. Install Dart:

    • In Terminal, run:

      brew tap dart-lang/dart
brew install dart
  3. Verify Installation:

    • Run the following command in Terminal:

      dart --version

For Linux

  1. Add the Dart APT repository:

    • Open Terminal and run:

      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 /etc/apt/sources.list.d/dart_stable.list https://storage.googleapis.com/download.dartlang.org/linux/debian/dart_stable.list'
  2. Install Dart:

    • Run:

      sudo apt update -y
sudo apt install dart
  3. Verify Installation:

    • Run:

      dart --version

Step 2: Set Up an IDE

Recommended IDEs

  • Visual Studio Code: A lightweight and powerful code editor with excellent Dart support.
  • IntelliJ IDEA: A feature-rich IDE with built-in support for Dart and Flutter.

Setting Up Visual Studio Code

  1. Install Visual Studio Code:
  2. Install Dart Extension:
    • Open Visual Studio Code.
    • Go to Extensions (Ctrl+Shift+X).
    • Search for "Dart" and install the Dart extension.
  3. Create a New Dart Project:
    • Open the terminal in Visual Studio Code (Ctrl+`).

    • Run the following command to create a new project:

      dart create my_first_app

    • Navigate to the project directory:

      cd my_first_app
  4. Run Your Dart Application:
    • Open the bin/my_first_app.dart file and modify it if you wish.

    • Run the application with:

      dart run

Setting Up IntelliJ IDEA

  1. Install IntelliJ IDEA:
  2. Install Dart Plugin:
    • Open IntelliJ IDEA.
    • Go to File > Settings > Plugins.
    • Search for "Dart" and install the plugin.
  3. Create a New Dart Project:
    • Go to File > New > Project.
    • Select Dart and click "Next".
    • Choose a project location and name, then click "Finish".
  4. Run Your Dart Application:
    • Open the main Dart file (usually lib/main.dart).
    • Click the green run button or right-click the file and select Run.

Step 3: Verify Your Setup

To ensure everything is set up correctly, create a simple Dart program:

  1. In your Dart project, open the bin directory.
  2. Create a new file named hello.dart.

  3. Add the following code:

    void main() {
  print('Hello, Dart!');
}

  4. Run the program:

    dart run bin/hello.dart

You should see the output:

Hello, Dart!

Congratulations! You have successfully installed and set up your Dart development environment. You can now start building applications using Dart. Explore the rich ecosystem and enjoy coding in Dart!
