debugOnRebuildDirtyWidget top-level property

RebuildDirtyWidgetCallback? debugOnRebuildDirtyWidget

getter/setter pair

Callback invoked for every dirty widget built each frame.

This callback is only invoked in debug builds.

See also:

debugPrintRebuildDirtyWidgets, which does something similar but logs to the console instead of invoking a callback.
debugOnProfilePaint, which does something similar for RenderObject painting.
WidgetInspectorService, which uses the debugOnRebuildDirtyWidget callback to generate aggregate profile statistics describing which widget rebuilds occurred when the ext.flutter.inspector.trackRebuildDirtyWidgets service extension is enabled.

Implementation

RebuildDirtyWidgetCallback? debugOnRebuildDirtyWidget;
