attach method

@override void attach(covariant PipelineOwner owner)

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(covariant PipelineOwner owner) {
  super.attach(owner);
  for (final child in _children) {
    child.attach(owner);
  }
  cursorCont.floatingCursorTextPosition.addListener(_onFloatingCursorChange);
  if (containsCursor()) {
    cursorCont.addListener(markNeedsLayout);
    cursorCont.color.addListener(safeMarkNeedsPaint);
    _attachedToCursorController = true;
  }
}
