如何注銷Facebook帳戶以輸入另一個帳戶-有解無憂

我正在使用顫振的 Facebook 身份驗證。

當我第一次登錄時輸入電子郵件和密碼，然后我注銷并再次登錄，然后它沒有要求輸入電子郵件和密碼。

它看起來像如何注銷 Facebook 帳戶以輸入另一個帳戶

這是我的 Facebook 登錄功能


import 'package:cwc/ApiManager/preference.dart';
import 'package:firebase_auth/firebase_auth.dart';
import 'package:flutter_facebook_auth/flutter_facebook_auth.dart';
final FirebaseAuth _auth = FirebaseAuth.instance;

// final GoogleSignIn googleSignIn = GoogleSignIn();

String? fbName;
String? fbEmail;
String? fbImageUrl;

Future<String?> signInWithFacebook() async {
  // Trigger the sign-in flow
  final LoginResult loginResult = await FacebookAuth.instance.login();
  // final GoogleSignInAccount? googleSignInAccount = await googleSignIn.signIn();
 var a= await loginResult.message;
  // Create a credential from the access token
  final OAuthCredential facebookAuthCredential = FacebookAuthProvider.credential(loginResult.accessToken!.token);
  print("facebookAuthCredential22 ${facebookAuthCredential.token}");
  print("facebookAuthCredential33 ${facebookAuthCredential.accessToken}");
  print("facebookAuthCredential44 ${facebookAuthCredential.rawNonce}");
  // Once signed in, return the UserCredential
  final UserCredential authResult =
  await _auth.signInWithCredential(facebookAuthCredential);
  final User? users = authResult.user;
  final UserInfo? user = users!.providerData[0];
  print("facebookAuthCredential11 $user");
  // return FirebaseAuth.instance.signInWithCredential(facebookAuthCredential);

  if (user != null) {
    // Checking if email and name is null
    // assert(user.email != null);
    assert(user.displayName != null);
    assert(user.photoURL != null);

    Preferences.saveData("socialName", user.displayName.toString());
    Preferences.saveData("socialEmail", user.email.toString());
    Preferences.saveData("socialImage", user.photoURL.toString());

    // Only taking the first part of the name, i.e., First Name
    // if (googleName!.contains(" ")) {
    //   googleName = googleName!.substring(0, googleName!.indexOf(" "));
    // }

    assert(!users.isAnonymous);
    assert(await users.getIdToken() != null);

    final User? currentUser = _auth.currentUser;
    assert(users.uid == currentUser!.uid);

    print('signInWithFacebook succeeded: $user');

    return '$user';
  }

  return null;
}

Future<void> signOutWithFacebook() async {
  await FacebookAuth.instance.logOut();
  print("User Signed Out");
}

uj5u.com熱心網友回復：

您還需要通過呼叫以下方式明確退出 Facebook：

FacebookAuth.instance.logOut()

另見：

退出時flutter_facebook_auth的檔案

uj5u.com熱心網友回復：

您可以在上呼叫該setCustomParameters()方法FacebookAuthProvider。

并像這樣傳遞同意引數：

_facebookAuth.setCustomParameters({"consent":"select_account"});

您可以閱讀有關可以傳遞給此答案的同意的引數
