当我使用 facebook flutter 登录时出现“FacebookLoginStatus.error”

问题描述

我用于登录 facebook 的代码与 Flutter firebase 不起作用。并且会得到 FacebookLoginStatus.error 的情况：

bool loading = false;
UserInfo user;
FirebaseAuth _auth = FirebaseAuth.instance;
static final FacebookLogin _facebookSignIn = new FacebookLogin();
Future _loginfb() async {
FacebookLoginResult result = await _facebookSignIn.logIn(['email']);

switch (result.status) {
  case FacebookLoginStatus.loggedIn:
    await _loginWithFb(result);
    break;
  case FacebookLoginStatus.cancelledByUser:
    setState(() => loading = false);
    print("bb");
    break;
  case FacebookLoginStatus.error:
    setState(() => loading = false);
    print(FacebookLoginStatus.error.index.toString() + " eee");
    break;
}
}
Future _loginWithFb(FacebookLoginResult _result) async {
FacebookAccesstoken _accesstoken = _result.accesstoken;
AuthCredential _credential =
    FacebookAuthProvider.getCredential(accesstoken: _accesstoken.token);
var a = await _auth.signInWithCredential(_credential);
setState(() {
  loading = true;
  user = a.user;
});
}

导入的包
