dependOnInheritedWidgetOfExactType<T extends InheritedWidget> abstract method
T?
dependOnInheritedWidgetOfExactType<T extends InheritedWidget>()
Obtains the nearest widget of the given type T
, which must be the type
of a concrete InheritedWidget subclass, and registers this build context
with that widget such that when that widget changes (or a new widget of
that type is introduced, or the widget goes away), this build context is
rebuilt so that it can obtain new values from that widget.
Implementation
T? dependOnInheritedWidgetOfExactType<T extends InheritedWidget>();
