Using context.dependOnInheritedWidgetOfExactType instead context.inheritFromWidgetOfExactType

[kranfix]

Provider use _DelegateElement and every custom element must have the same api of Element, then the following actions were done:

• Updated _DelegateElement deprecating inheritFromElement in favor of inheritFromElement.
• Updated static Provider.of

final provider = listen
        ? context.dependOnInheritedWidgetOfExactType<InheritedProvider<T>>()
        : context
            .getElementForInheritedWidgetOfExactType<InheritedProvider<T>>()
            ?.widget as InheritedProvider<T>;
