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. [...]
override

debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node. [...]
override
-
updateRenderObject(
BuildContext context, covariant 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. [...]
override
-
createElement(
) → SingleChildRenderObjectElement -
RenderObjectWidgets always inflate to a RenderObjectElement subclass.
inherited
-
debugDescribeChildren(
) → List< DiagnosticsNode> -
Returns a list of DiagnosticsNode objects describing this node's
children. [...]
@protected, inherited
-
didUnmountRenderObject(
covariant RenderObject renderObject) → void -
A render object previously associated with this widget has been removed
from the tree. The given RenderObject will be of the same type as
returned by this object's createRenderObject.
