Constants
- everyFrame → const WidgetUpdatePolicy
- Capture every frame while attached (the default). Captures are throttled to one in flight, and the recording itself reuses the child's retained layers, so the steady-state cost is rasterizing the content that is actually changing.
- manual → const WidgetUpdatePolicy
- Capture only when WidgetTextureController.requestCapture is called.
