attach method

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

Mark this node 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 first call their inherited attach method, and then attach all their children to the same owner.

Implementations of this method should start with a call to the inherited method, as in super.attach(owner).


void attach(PipelineOwner owner) {
  // If there's a pending callback that would imply this node was detached
  // between the idle phase and the next transientCallbacks phase. The tree
  // can not be mutated between those two phases so that should never happen.
