TrinityDevToolsExtension class

The main DevTools extension widget for Flutter Debug Trinity.

Provides a tabbed interface with:

  • Timeline: Chronological stream of all Trinity events
  • Graph: Interactive causal DAG visualization
  • Explanations: Layout overflow analysis with fix suggestions

Usage as DevTools Extension

This widget is designed to be the root of a Flutter DevTools extension. Register it as a DevTools extension in your pubspec.yaml:

# In the extension's pubspec.yaml
devtools:
  extension:
    name: flutter_debug_trinity
    issueTracker: https://github.com/chirag640/flutter_debug_trinity/issues

Usage as In-App Overlay

You can also embed this directly in your app for on-device debugging:

// Show as a bottom sheet
showModalBottomSheet(
  context: context,
  isScrollControlled: true,
  builder: (_) => SizedBox(
    height: MediaQuery.of(context).size.height * 0.8,
    child: const TrinityDevToolsExtension(),
  ),
);
