repaintRequested property
Listenable
get
repaintRequested
Notifies when the scene wants painting again outside any repaint the
app drives: a screen view held its previous image because the GPU was
maxGpuFramesInFlight frames behind, and that work has now finished.
SceneView listens. A custom painter that repaints only on demand
should pass this as its repaint, or the held frame never shows.
Implementation
Listenable get repaintRequested => _repaintRequested;
