facebook login showing only previous logged in account in flutter app

Question

I have successfully integrated the facebook login in the flutter application and able to login.

But it is always the same account I am able to login and it does not show me any other option to login other than the previous facebook account. Below is the code which I executed.

Future<void> handleLogin() async {
  final FacebookLoginResult result = await facebookLogin.logIn(['email']);
  switch (result.status) {
    case FacebookLoginStatus.cancelledByUser:
      break;
    case FacebookLoginStatus.error:
      break;
    case FacebookLoginStatus.loggedIn:
      try {
        await loginWithfacebook(result);
      } catch (e) {
        print(e);
      }
      break;
  }
}

Future loginWithfacebook(FacebookLoginResult result) async {
  final FacebookAccessToken accessToken = result.accessToken;
  AuthCredential credential =
  FacebookAuthProvider.credential(accessToken.token);
  var a = await _auth.signInWithCredential(credential);
  setState(() {
    isSignIn = true;
    _user = a.user;
  });
}

Future<void> gooleSignout() async {
  await _auth.signOut().then((onValue) {
    setState(() {
      facebookLogin.logOut();
      isSignIn = false;
    });
  });
}

Please suggest the modification of the code to remove the previous sign in through the facebook. Screenshot of the screen I see as always

Solution

Open your default Web browser and navigate to Facebook.com. Then logout from your Facebook account.
