✅ Inherited controller should be attached
✅ Opening keyboard does not interrupt sheet animation
SheetKeyboardDismissible
  ✅ should dismiss the keyboard when dragging
  ✅ should dismiss the keyboard when scrolling

✅ FixedBouncingBehavior returns same value for same input metrics
✅ DirectionAwareBouncingBehavior respects gesture direction
SheetPhysics subclasses
  ✅ can create dynamic inheritance relationships
Default configuration of SheetPhysics
  ✅ does not allow over/under dragging
  ✅ does not apply any resistance if position is in bounds
  ✅ prevents position from going out of bounds
  ✅ creates no ballistic simulation if position is in bounds
  ✅ creates ballistic simulation which ends at the nearest edge
  ✅ creates no settling simulation if the position is in bounds
  ✅ creates settling simulation which ends at nearest edge
SnapToNearestEdge
  ✅ snaps to nearest edge if velocity is small enough
  ✅ is aware of fling gesture direction
  ✅ is disabled if position is out of bounds
SnapToNearest
  ✅ snaps to nearest edge if velocity is small enough
  ✅ is aware of fling gesture direction
  ✅ is disabled if position is out of bounds
BouncingSheetPhysics
  ✅ progressively applies friction if position is out of bounds
  ✅ does not allow to go beyond bounceable bounds
  ✅ applies friction even if position is on boundary
  ✅ can apply a reasonable friction to extremely large offset

✅ Drag gesture should dispatch drag start/update/end notifications in sequence
✅ Sheet animation should dispatch metrics update notifications
✅ Over-darg gesture should dispatch both darg and overflow notifications

Ignore pointer test:
  ✅ pointer events on a sheet should be ignored if activity says to do so
  ✅ content in a sheet should receive pointer events if activity allows
  ✅ content obscured by a sheet should never receive pointer events
  ✅ content not obscured by a sheet should always receive pointer events

✅ Attached controller emits correct pixel values when dragging
