onTick property

SceneTickCallback? onTick
final

Called once per frame while ticking. See SceneTickCallback.

When the view is gated by loading or loadingBuilder, it is not called while the loading widget is shown (per-frame app logic stays paused until the scene is revealed), and its first call after reveal carries a single-frame delta rather than the whole loading time.

Implementation

final SceneTickCallback? onTick;
