Methods

attach(RenderObject child) → void: inherited
clearPaintDirty() → void: Marks this render object's paint state as clean.
inherited
clearPaintDirtySubtree() → void: Marks this render object and all descendants as paint-clean.
inherited
detach(RenderObject child) → void: inherited
dispose() → void: inherited
hitTest(HitTestResult result, {required double localX, required double localY}) → bool: Performs hit-testing at (localX, localY) in this object's coordinate space. Adds matching entries to result, deepest first.
inherited
layout(BoxConstraints constraints) → void: override
markDescendantNeedsPaint() → void: Called when a descendant render object's paint output has changed.
inherited
markNeedsPaintOnly() → void: Marks this render object as needing paint without invalidating descendant-specific paint caches.
inherited
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
paint() → String: override
toString() → String: A string representation of this object.

Operators

operator ==(Object other) → bool: The equality operator.
