IgnorePointer class

A widget that is invisible during hit testing.

When ignoring is true, this widget (and its subtree) is invisible to hit testing. It still consumes space during layout and paints its child as usual. It just cannot be the target of located events, because it returns false from RenderBox.hitTest.

When ignoringSemantics is true, the subtree will be invisible to the semantics layer (and thus e.g. accessibility tools). If ignoringSemantics is null, it uses the value of ignoring.

  • AbsorbPointer, which also prevents its children from receiving pointer events but is itself visible to hit testing.

Methods

createRenderObject(BuildContext context) RenderIgnorePointer
Creates an instance of the RenderObject class that this RenderObjectWidget represents, using the configuration described by this RenderObjectWidget. [...]
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
updateRenderObject(BuildContext context, RenderIgnorePointer renderObject) → void
Copies the configuration described by this RenderObjectWidget to the given RenderObject, which will be of the same type as returned by this object's createRenderObject. [...]
createElement() SingleChildRenderObjectElement
RenderObjectWidgets always inflate to a RenderObjectElement subclass.

debugDescribeChildren() List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children. [...]
