install-flutter-from-git

This skill guides you through installing the Flutter SDK using git clone and setting up the environment for Web, Mobile, and Desktop development.

1. Prerequisites (All Platforms)

Ensure you have the following installed:

• Git: Install Git
• Curl/Unzip (macOS/Linux usually have these; Windows usually needs Git Bash or similar)

2. Install Flutter SDK

macOS / Linux

Open your terminal and run the following commands to clone the stable branch of the Flutter SDK.

# Create a directory for development (e.g., ~/development)
mkdir -p ~/development
cd ~/development

# Clone the Flutter SDK
git clone https://github.com/flutter/flutter.git -b stable

Windows

Open PowerShell or Command Prompt.

# Create a directory for development (e.g., C:\src)
mkdir C:\src
cd C:\src

# Clone the Flutter SDK
git clone https://github.com/flutter/flutter.git -b stable

3. Add Flutter to PATH

To run flutter commands from any terminal, you must add the SDK's bin directory to your PATH.

macOS (Zsh) / Linux (Bash/Zsh)

1. Open your shell configuration file (e.g., ~/.zshrc, ~/.bashrc, or ~/.zshenv).

2. Add the following line (replace ~/development/flutter with your actual path):

   export PATH="$PATH:$HOME/development/flutter/bin"
   

3. Refresh your current terminal:

   source ~/.zshrc  # or ~/.bashrc
   

Windows

1. Press Win + S, type "env", and select Edit the system environment variables.
2. Click Environment Variables.
3. Under User variables, select Path and click Edit.
4. Click New and add the full path to flutter\bin (e.g., C:\src\flutter\bin).
5. Click OK on all windows.
6. Restart your terminal/PowerShell.

4. Verify Installation

Run the following command to check for missing dependencies:

flutter doctor

5. Platform Setup

Web (Chrome)

1. Install Chrome: Ensure Google Chrome is installed.
2. Enable Web Support (usually enabled by default):

   flutter config --enable-web
   

3. Verify: Run flutter devices to see "Chrome" listed.

Mobile (iOS & Android)

iOS (macOS only)

1. Install Xcode: Download from the Mac App Store.
2. Configure Command Line Tools:

   sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer
   sudo xcodebuild -runFirstLaunch
   

3. Install CocoaPods (for dependency management):

   sudo gem install cocoapods
   

4. Simulator: Open via open -a Simulator.

Android (All Operating Systems)

1. Install Android Studio: Download here.
2. Install SDK Components:
   • Open Android Studio -> SDK Manager.
   • Install Android SDK Platform-Tools.
   • Install Android SDK Command-line Tools (latest).
3. Accept Licenses:

   flutter doctor --android-licenses
   

   (Press y to accept all licences).
4. Emulator: Create a device in AVD Manager.

Desktop (macOS, Windows, Linux)

macOS Desktop

1. Install Xcode: (Same as iOS steps above).
2. Enable macOS:

   flutter config --enable-macos-desktop
   

Windows Desktop

1. Install Visual Studio (not VS Code): Download VS Community.
2. Workloads: When installing, select Desktop development with C++.
3. Enable Windows:

   flutter config --enable-windows-desktop
   

Linux Desktop

1. Install Dependencies (Ubuntu/Debian example):

   sudo apt-get update
   sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev liblzma-dev
   

2. Enable Linux:

   flutter config --enable-linux-desktop
   

6. Final Check

Run flutter doctor again to ensure all desired platforms have checkmarks.

flutter doctor -v
