Add required development dependencies to `pubspec.yaml`: ```bash flutter pub add 'dev:integration_test:{"sdk":"flutter"}' flutter pub add 'dev:flutter_test:{"sdk":"flutter"}' ``` 2. Enable the Flutter Driver extension in your application entry point (typically `lib/main.dart` or a dedicated `lib/main_test.dart`): - Import `package:flutter_driver/driver_extension.dart`. - Call `enableFlutterDriverExtension();` before `runApp()`. 3. Add `Key` parameters (e.g., `ValueKey('login_button')`) to critical widgets in the application code to ensure reliable targeting during tests. ## Interactive Exploration via MCP Use the Dart/Flutter MCP server tools to interactively explore and manipulate the application state before writing static tests. - **Launch**: Execute `launch_app` with `target: "lib/main_test.dart"` to start the application and acquire the DTD URI. - **Inspect**: Execute `get_widget_tree` to discover available `Key`s, `Text`
