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.
