hitTestChildren method

  1. @override
bool hitTestChildren (BoxHitTestResult result, { Offset position })
override

Override this method to check whether any children are located at the given position.

Typically children should be hit-tested in reverse paint order so that hit tests at locations where children overlap hit the child that is visually "on top" (i.e., paints later).

The caller is responsible for transforming position from global coordinates to its location relative to the origin of this RenderBox. This RenderBox is responsible for checking whether the given position is within its bounds.

If transforming is necessary, HitTestResult.addWithPaintTransform, HitTestResult.addWithPaintOffset, or HitTestResult.addWithRawTransform need to be invoked by the caller to record the required transform operations in the HitTestResult. These methods will also help with applying the transform to position.

Used by hitTest. If you override hitTest and do not call this function, then you don't need to implement this function.

Implementation

@override
bool hitTestChildren(BoxHitTestResult result, { Offset position }) {
  return defaultHitTestChildren(result, position: position);
}
