removeAll method

@override void removeAll()

Remove all their children from this render object's child list.

More efficient than removing them individually.

Implementation

@override
void removeAll() {
  super.removeAll();
  _cachedPaintingOrder = null;
  markNeedsIntrinsicMeasurementUpdate('childListRemoveAll');
  _markNearestInlineFormattingContextDirty();
}
