flutter_agent_lens 1.5.2

Agent-first MCP server to debug, profile, and optimize running Flutter apps.

1.5.2

• Deprecated and removed the redundant dual format option across all tools to optimize token usage.
• Updated tool schemas and test_all_tools.dart to specify either markdown or json.

1.5.1

• Split the monolithic server file into 12 separate class mixins for better maintainability.
• Consolidated the tool list in the README file.

1.5.0

• Subscribed to onServiceEvent before calling streamListen(EventStreams.kService) in connection_handlers.dart to resolve a VM service discovery race condition.
• Routed handleHotReload and handleHotRestart through DTD service calls if DTD is active, VM service callbacks (s1.reloadSources with isolateId and s1.hotRestart) if available, or isolate-level extensions as a fallback.
• Added dependency on dtd package to support direct Dart Tooling Daemon communication.

1.4.1

• Refactored and optimized internal MCP tool handlers for widget tracking, memory diffing, and network capturing.
• Parameterized location map parsers (_parseLocationsMap and _parseNewLocationsMap) to remove local duplicates and share code across rebuild tracking handlers.
• Standardized class allocation diff tables and sorted delta logic into shared helpers in memory_handlers.dart.
• Converted local size formatting (formatSize) in network_handlers.dart and memory_handlers.dart to a library-wide unified _formatBytes helper on FlutterAgentLensServer.
• Consolidated rebuild tracking availability checks under _isTrackRebuildSupported().

1.4.0

• Added a format parameter (markdown, json, dual) to verbose tools so clients can drop JSON and base64 payloads when they're not needed.
• get_cpu_profile now filters out functions with 0 ticks before returning results, cutting payload size by ~99% on typical profiles.
• Added includeRawNode to inspect_widget and includeRawResponse to get_object_referrers and stop_network_capture. Both default to false, skipping large raw VM payloads unless requested.
• diff_heap_allocations now returns only the top 50 classes with allocation changes instead of the full list.
• stop_tracking_rebuilds and get_widget_rebuild_counts cap rebuild lists to the top N active widgets.
• Added includeExtensions to get_app_info (defaults to false). Omits the 60+ registered Flutter service extensions, saving ~3-4 KB per call.
• Removed decorative separators (===, ---), markdown headings (###, **bold**), backtick wrapping, and column-alignment padding (.padLeft(), .padRight()) from all tool response output paths. Plain text labels replace them throughout.
• Migrated compare_snapshots to the _serializeDualFormat path, adding format parameter support and structured JSON output.
• All tool response sizes reduced by 15-40% with no semantic information removed.

1.3.0

• Added stateful tracking tools: start_tracking_rebuilds / stop_tracking_rebuilds, start_profiling / stop_profiling, and start_network_capture / stop_network_capture.
• Added the get_memory_snapshot tool to list active class allocations.
• Added connection warnings when a Dart Tooling Daemon (DTD) URI is passed to connect.
• Fixed hot reload and hot restart hangs by dynamically checking service namespaces.
• Fixed isolate ID and library cache clearing after a hot restart.

1.2.0

• Added take_screenshot tool to capture native or Skia device screenshots, with automatic fallback to native captures when Impeller is active.
• Added hot_restart tool to trigger application state resets, with improved diagnostic messages when running without a host connection.
• Added get_widget_tree tool to recursively retrieve the active widget tree with local project widget filtering.
• Added memory snapshot tools (save_snapshot, compare_snapshots, list_snapshots) to cache and calculate class allocation differences.

1.1.0

• Added the compare_layout_screenshots tool to capture, verify, and highlight visual differences in layout screens.
• Added parameters to select the capture type (device or skia) and specify target devices.

1.0.0

• Initial version.
