AuthProvider<T extends Auth<AuthKeys>> class

Provides an Authorizer to the widget tree.

IMPORTANT: authorizer কে AuthProvider এর বাইরে State এ তৈরি করো। build() এর ভেতরে new Authorizer() করলে rebuild এ নতুন instance হয়।

// ✅ সঠিক — State এ তৈরি
class _MyState extends State<MyWidget> {
  late final _authorizer = Authorizer<User>(...);

  Widget build(BuildContext context) {
    return AuthProvider<User>(authorizer: _authorizer, child: ...);
  }
}

// ❌ ভুল — build() এ তৈরি
Widget build(BuildContext context) {
  return AuthProvider<User>(
    authorizer: Authorizer<User>(...), // প্রতি rebuild এ নতুন instance!
    child: ...,
  );
}

Properties

authorizer → Authorizer<T>
Widget tree এ expose করার Authorizer। State এ তৈরি করা instance pass করো।
final
child → Widget
final
createInstance → bool
true হলে global singleton হিসেবে register করে। সাধারণত false রাখো — Root এ নিজে dispose করো।
final
hashCode → int
The hash code for this object.
no setterinherited
initialCheck → bool
Cold start এ cache থেকে user emit করবে কিনা। true রাখো — hot reload এ user null আসবে না।
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
listening → bool
Realtime auth state changes listen করবে কিনা।
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited

inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String
Returns a string representation of this node and its descendants.
