AI summary
Auto-generated overview of what this skill does and when to reach for it.
Suite of performance tools for debugging and profiling Dart and Flutter apps.
Use this when
- Flutter app runs slowly and you need to find bottlenecks
- Memory usage is unexpectedly high and you need to track leaks
- App crashes intermittently and you need to inspect stack traces
- Widget rebuilds are happening too often and you need to analyze performance
- Network requests are slow and you need to inspect payloads
Don't use when
- You need to design UI layouts (use Flutter Inspector instead)
- You need to edit code directly (use an IDE instead)
- You need to test app functionality (use Flutter test instead)
Capabilities
- Flame graph for CPU profiling
- Memory allocation tracking and leak detection
- Network request/response inspection
- Widget rebuild analysis
- Timeline view for app events
- Heap snapshot comparison
