snap property Null safety

bool snap
final

Whether the widget should snap between snapSizes when the user lifts their finger during a drag.

If the user's finger was still moving when they lifted it, the widget will snap to the next snap size (see snapSizes) in the direction of the drag. If their finger was still, the widget will snap to the nearest snap size.

Rebuilding the sheet with snap newly enabled will immediately trigger a snap unless the sheet has not yet been dragged away from initialChildSize since first being built or since the last call to DraggableScrollableActuator.reset.

Implementation
