import 'package:flutter/material.dart';
import 'package:time_tracker_flutter_course/services/auth.dart';

//Provider 직접 생성
class AuthProvider extends InheritedWidget {
AuthProvider({@required this.auth, @required this.child});
final AuthBase auth;
final Widget child;

@override
bool updateShouldNotify(InheritedWidget oldWidget) => false;

//final auth =AuthProvider.of(context);
// static 정적 선언 메서드 ?아무데서나 호출 가능
static AuthBase of(BuildContext context) {
AuthProvider provider =
context.dependOnInheritedWidgetOfExactType<AuthProvider>();
return provider.auth;
}
}
