ctrl s is required to update the UI while I am using provider-CodePudding

I am building an auth screen where i am using isLogin boolean... I created a method to change the value of isLogin but it requires ctrl s or use SetState() to change the value and update UI... here is the Provider class code

  bool _isLogin = true;
  bool get isLogin => _isLogin;
  changeAuth(value) {
    _isLogin = value;
    notifyListeners();
  }

here I am calling method

   TextButton(
                            onPressed: () {
                              auth.changeAuth(
                                  auth.isLogin == true ? false : true);
                           
                            },
                            child: Text(
                              auth.isLogin
                                  ? "Register a new account"
                                  : "Login instead",
                              style: const TextStyle(
                                  decoration: TextDecoration.underline,
                                  color: Colors.blue),
                            ))

CodePudding user response：

If auth is Provider

 TextButton(
                            onPressed: () {
                              context.read<ProviderClassName>().changeAuth(
                                  context.read<ProviderClassName>().isLogin == true ? false : true);
                           
                            },
                            child: Text(
                              context.watch<ProviderClassName>().isLogin
                                  ? "Register a new account"
                                  : "Login instead",
                              style: const TextStyle(
                                  decoration: TextDecoration.underline,
                                  color: Colors.blue),
                            ))
