android - 使用 Facebook 登录时无法切换帐户

Question

该应用程序允许用户使用 Facebook 登录，但当用户想要使用不同的 Facebook 帐户登录时，我遇到了问题，此页面只会显示继续按钮。有没有办法让用户选择使用不同的帐户进行登录？

   Future<User> signInWithFacebook() async {
    final fb = FacebookLogin();
    final response = await fb.logIn(permissions: [
      FacebookPermission.publicProfile,
      FacebookPermission.email,
    ]);

    switch (response.status) {
      case FacebookLoginStatus.Success:
        final accessToken = response.accessToken;
        final userCredential = await _firebaseAuth.signInWithCredential(
          FacebookAuthProvider.credential(accessToken.token),
        );
        return userCredential.user;

      case FacebookLoginStatus.Cancel:
        throw FirebaseAuthException(
          code: 'ERROR_ABORTED_BY_USER',
          message: 'Sign in aborted by user',
        );
      case FacebookLoginStatus.Error:
        throw FirebaseAuthException(
          code: 'ERROR_FACEBOOK_LOGIN_FAILED',
          message: response.error.developerMessage,
        );
      default:
        throw UnimplementedError();
    }
  }
  @override
  Future<void> signOut() async {
    final googleSignIn = GoogleSignIn();
    await googleSignIn.signOut();
    final facebookLogin = FacebookLogin();
    await facebookLogin.logOut();
    await _firebaseAuth.signOut();
  }```
