forRectOf static method

DragBoundaryDelegate<Rect> forRectOf(
  1. BuildContext context, {
  2. bool useGlobalPosition = true,
})

Retrieve the DragBoundary from the nearest ancestor to get its DragBoundaryDelegate of Rect.

The useGlobalPosition specifies whether to retrieve the DragBoundaryDelegate of type Rect in global coordinates. If false, the local coordinates of the boundary are used. Defaults to true.

If no DragBoundary ancestor is found, the delegate will return a delegate that allows the drag object to move freely.

Implementation

static DragBoundaryDelegate<Rect> forRectOf(
  BuildContext context, {
  bool useGlobalPosition = true,
}) {
  return forRectMaybeOf(context, useGlobalPosition: useGlobalPosition) ??
      _DragBoundaryDelegateForRect(null);
}
