FixedBouncingBehavior class

A BouncingBehavior that allows the sheet position to exceed the content bounds by a fixed amount.

The following is an example of a BouncingSheetPhysics that allows the sheet position to go beyond the SheetMetrics.maxPixels or SheetMetrics.minPixels by 12% of the content size.

const physics = BouncingSheetPhysics(
  behavior: FixedBouncingBehavior(SheetAnchor.proportional(0.12)),
);
