AbsorbPointer class

A complete pointer boundary: the cells this widget covers consume every pointer interaction — taps, secondary taps, drags, wheel scroll, hover — and block the dispatcher's click-to-focus, so nothing painted underneath can be invisibly activated, scrolled, hovered, or focused.

This is the input counterpart of painting an opaque overlay: an overlay that covers cells visually must also cover them for input, or clicks fall through to hidden widgets. The debug shell's floating panel uses this boundary. Its descendant controls remain interactive: hit testing visits them before the boundary and stops here before reaching content behind it.

Methods

animate({Duration? duration, Curve? curve, Object? trigger, bool repeat = false}) → Animate

Available on Widget, provided by the AnimateExtension extension

Starts an Animate chain over this widget. duration / curve apply to the whole chain. With no trigger it plays on mount; with a non-null trigger it rests on mount and replays whenever the token changes.

createElement() → SingleChildRenderObjectElement

Creates the Element that will mount this widget into the tree.

override

createRenderObject(BuildContext context) → RenderObject

Creates the render object backing this widget. Called once when the element first mounts.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

updateRenderObject(BuildContext context, covariant RenderPointerListener renderObject) → void

Applies any changes from a new widget instance to the existing render object. Default is a no-op; subclasses override when the widget carries layout/paint configuration.

override

Operators

operator ==(Object other) → bool

The equality operator.
