findRootAncestorStateOfType<T extends State<StatefulWidget> > method
Null safety
Returns the State object of the furthest ancestor StatefulWidget widget
that is an instance of the given type T
.
Functions the same way as findAncestorStateOfType but keeps visiting subsequent
ancestors until there are none of the type instance of T
remaining.
Then returns the last one found.
This operation is O(N) as well though N is the entire widget tree rather than a subtree.
Implementation
T? findRootAncestorStateOfType<T extends State>();
