Use Type with Flutter Hooks


I was trying to add different useState in my page with Flutter hook but i can’t find a way to do it by giving them a type first, because of the inital value requested.

i can’t initialize my useState with :

QRViewController? controller = useState();


final controller = useState<QRViewController>()


QRViewController? controller = useState(null);

How can i initialized controller with custom type ?


final ValueNotifier<QRViewController?> controller = useState(null);


final controller = useState<QRViewController?>(null);

You were very close.
