GoCart — Flutter App with Build Flavors

This project uses Flutter build flavors to generate and run three separate versions of the app:

• Instance A
• Instance B
• Instance C

Each version has its own entrypoint and configuration.

---

🚀 Running the App (Flavors)

Instance A

flutter run --flavor instanceA -t lib/main_a.dart

Instance B

flutter run --flavor instanceB -t lib/main_b.dart

Instance C

flutter run --flavor instanceC -t lib/main_c.dart

---

🛠 Building APKs (Per Flavor)

Instance A

flutter build apk --flavor instanceA -t lib/main_a.dart 

Instance B

flutter build apk --flavor instanceB -t lib/main_b.dart 

Instance C

flutter build apk --flavor instanceC -t lib/main_c.dart 

---

🛠 Windows Executable

flutter build windows -t lib/main_a.dart

---

VS Code Setup (Optional)

To run flavors easily in VS Code, use the predefined launch configurations in .vscode/launch.json.

Example launch configuration:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "Instance A",
      "request": "launch",
      "type": "dart",
      "program": "lib/main_a.dart",
      "args": ["--flavor", "instanceA"]
    },
    {
      "name": "Instance B",
      "request": "launch",
      "type": "dart",
      "program": "lib/main_b.dart",
      "args": ["--flavor", "instanceB"]
    },
    {
      "name": "Instance C",
      "request": "launch",
      "type": "dart",
      "program": "lib/main_c.dart",
      "args": ["--flavor", "instanceC"]
    }
  ]
}

To use:

1. Open the Run and Debug panel in VS Code.
2. Select the desired configuration (e.g., "Instance A").
3. Click ▶️ to launch.

Requirements

• Flutter 3.7.3 (or compatible)
• Dart SDK 3.7+
• Android Studio or VS Code with Flutter plugin
• Android SDK (for building APKs)

---

Flavor Entry Files

• lib/main_a.dart
• lib/main_b.dart
• lib/main_c.dart

Each entry file initializes an AppConfig and passes it to MyApp in lib/app.dart.

The shared app logic and UI lives in lib/app.dart, which builds the app according to the provided flavor configuration.
