Flutter Inspector MCP Server

# Progress **Status:** Object Group Management - Planning Complete. **What Works:** - Basic project structure exists. - Detailed implementation plan for Object Group Management is created: `devtools_mcp_extension/object_group_implementation_plan.md`. - Added `uuid` dependency to `devtools_mcp_extension/pubspec.yaml` and ran `flutter pub get`. - Created `ObjectGroup` and `ObjectGroupManager` classes in `devtools_mcp_extension/lib/services/object_group_manager.dart`. - Integrated `ObjectGroupManager` into `DevtoolsService`. - Refactored `getRootWidget` method in `DevtoolsService` to use `ObjectGroupManager`. - Verified generic `callServiceExtension` method in `DevtoolsService`. **What's Left:** - Implement Object Group Management in `devtools_mcp_extension` (following the plan). - Implement the core functionality of the MCP server, DevTools extension, and forwarding server. - Implement specific RPC methods. **Known Issues:** The README mentions that not all Flutter Inspector related methods are implemented yet. ### Progress: Implementing `getErrors` Function **What Works:** - Initial plan for `getErrors` function is defined. - Research into DevTools codebase and VM service interaction is underway. - Understanding of `ObjectGroup` pattern and its importance is established. - Refined plan incorporating remote diagnostics and object groups is in place. **What's Left to Build:** - Implement the `getErrors` function in `custom_devtools_service.dart`. - Remote diagnostics tree retrieval using `getRootWidgetTree`. - Tree traversal and error detection logic based on `RemoteDiagnosticsNode` properties. - Integration of `ObjectGroupManager`. - Data formatting for error reporting. - Write unit and integration tests for `getErrors`. - Further research to refine error detection logic and categorization. **Current Status:** - Planning and research phase is nearing completion. - Implementation phase is about to begin. - Key technical decisions regarding remote diagnostics and object groups are made. **Known Issues & Open Questions:** - **Error Detection Logic Details:** Need to pinpoint the exact error detection logic in DevTools codebase. (Follow-up question 1 in the refined plan). - **Example Error Node JSONs:** Need example JSON structures of error nodes for robust error detection pattern creation. (Follow-up question 2 in the refined plan). - **Error Categorization:** Error types are currently strings; consider refining to enums later. - **Performance:** Performance implications of tree traversal and remote diagnostics calls need to be considered during implementation and testing. **Evolution of Project Decisions:** - **Initial Approach (Incorrect):** Initially considered using local `WidgetsBinding.instance.rootElement` for inspection, which was identified as incorrect. - **Current Approach (Corrected):** Shifted to using remote diagnostics nodes via VM service for accurate representation of the debuggable application's tree. - **Memory Management:** Recognized the importance of `ObjectGroup` pattern from DevTools for memory management and incorporated it into the plan.
