attach method

  1. @override
void attach(
  1. PipelineOwner owner
)
override

Mark this render object as attached to the given owner.

Typically called only from the parent's attach method, and by the owner to mark the root of a tree as attached.

Subclasses with children should override this method to attach all their children to the same owner after calling the inherited method, as in super.attach(owner).

Implementation

@override
void attach(PipelineOwner owner) {
  super.attach(owner);
  _foregroundRenderObject?.attach(owner);
  _backgroundRenderObject?.attach(owner);

  _tap = TapGestureRecognizer(debugOwner: this)
    ..onTapDown = _handleTapDown
    ..onTap = _handleTap;
  _longPress = LongPressGestureRecognizer(debugOwner: this)..onLongPress = _handleLongPress;
  _offset.addListener(markNeedsPaint);
  _showHideCursor();
  _showCursor.addListener(_showHideCursor);
}
