Flutter & Java JDK Setup

Setting up your development environment correctly ensures a smooth experience while building Flutter applications. Follow these steps to install Flutter, configure Java JDK, set up your IDE, and initialize your project.

1️⃣ Install Flutter 🛠️​

  • Download the Flutter SDK from the official site: Flutter SDK

  • Extract the ZIP file to a suitable location (e.g., C:\flutter on Windows or ~/flutter on macOS/Linux).

  • Add Flutter to your system path:

    • Windows: Add C:\flutter\bin to System Environment Variables.
    • macOS/Linux: Add export PATH="$HOME/flutter/bin:\$PATH" to ~/.zshrc or ~/.bashrc.

  • Run the following command to verify installation:

    flutter doctor --verbose

  • ✅ Ensure all dependencies are installed before proceeding.

2️⃣ Install Java JDK ☕​

  • Download the latest Java Development Kit (JDK) from Oracle or OpenJDK.

  • Install the JDK and note the installation path.

  • Set up environment variables:

    • Windows:

      • Add JAVA_HOME as the JDK installation path in system variables.
      • Add %JAVA_HOME%\bin to the Path variable.

    • macOS/Linux:

      export JAVA_HOME=$(/usr/libexec/java_home)
      export PATH=$JAVA_HOME/bin:$PATH

  • Verify installation:

    java -version

  • ✅ Ensure Java is installed correctly before proceeding.

3️⃣ Install IDE 🖥️​

To develop Flutter applications efficiently, install an appropriate IDE:

  • Android Studio (Recommended for full Android development tools)

    • Download from: Android Studio
    • Install Flutter & Dart plugins from Preferences > Plugins.

  • Visual Studio Code (VS Code) (Lightweight & fast)

    • Download from: VS Code
    • Install the Flutter and Dart extensions from the Extensions Marketplace.

✅ Choose the IDE that best fits your workflow and install the necessary plugins.

4️⃣ Basic Flutter Project Setup 📂​

  • Run the project on an emulator or connected device:

    flutter run

  • Configure Android & iOS:

    • Android: Install Android Studio & necessary SDKs.
    • iOS (macOS only): Install Xcode & set up the iOS simulator.

✅ Final Check:

  • Ensure Flutter, Java, and IDE are correctly installed by running:

    flutter doctor

  • Resolve any missing dependencies.

  • Test a simple Flutter app to confirm everything works as expected.
