Fix broken test infrastructure where MockProcess.stdin threw UnimplementedError, making it impossible to test any functionality that writes to process stdin. This was a bug in the test mock that prevented testing stdin-based features like hot restart commands. Changes: - Replace UnimplementedError with functional MockIOSink implementation - Implement writeln, flush, and close methods - Add state tracking for verification in tests
Implement hot restart functionality to allow restarting Flutter applications without terminating the debug session. The tool sends the 'R' command to the running process's stdin, triggering a full application restart while maintaining the connection. Changes: - Add hotRestartTool definition with input/output schemas - Implement _hotRestart handler method - Register hot_restart tool in initialize method - Add error handling for non-existent process IDs
Add comprehensive test coverage for the hot_restart tool, including success and error scenarios. Tests added: - Successful hot restart on running application - Error handling for non-existent process ID
Update documentation to include the new hot_restart tool in the list of available MCP server tools. Changes: - Add hot_restart to tool list in main README - Add hot_restart API documentation in flutter_launcher_mcp README - Include input/output schemas for the tool

amazing, thank you! We really appreciate this contribution! Apologies, but would you be willing to make a patch over here: https://github.com/dart-lang/ai/tree/main/pkgs/dart_mcp_server ? We're going to actually move these MCP tools in the extension over to the dart/flutter MCP server. You could help close out dart-lang/ai#254 |

hot_restarttool to theflutter_launcherMCP server. Works the same as pressing 'R' in the terminal duringflutter run, it restarts the app without killing the debug session.hot_restarttool that sends 'R' command to process stdin
