flutter - Twitter 身份验证不起作用，并且没有显示具有用户名的主屏幕

Question

我正在尝试通过https://developer.twitter.com/获取 Auth 用户

当我单击登录时，我使用模拟器在终端中找到了以下代码：

这是以下身份验证设置：

当我在按下登录后尝试进行身份验证时，它会以下面的屏幕结束，并且不会返回主屏幕以显示用户名......：

这是下面的代码：

import 'package:flutter/material.dart';
import 'package:flutter_twitter_login/flutter_twitter_login.dart';

void main() {
  runApp(MaterialApp(
    debugShowCheckedModeBanner: false,
    home: TwitterLoginScreen(),
  ));
}

class TwitterLoginScreen extends StatefulWidget {
  @override
  _TwitterLoginScreenState createState() => _TwitterLoginScreenState();
}

class _TwitterLoginScreenState extends State<TwitterLoginScreen> {
  static final TwitterLogin twitterLogin = TwitterLogin(
    consumerKey: 'consumerKey',
    consumerSecret: 'consumerSecret',
  );

  String _title="";

  void _login() async {
    final TwitterLoginResult result = await twitterLogin.authorize();
    String Message;

    switch (result.status) {
      case TwitterLoginStatus.loggedIn:
        Message = 'Logged in! username: ${result.session.username}';
        break;
      case TwitterLoginStatus.cancelledByUser:
        Message = 'Login cancelled by user.';
        break;
      case TwitterLoginStatus.error:
        Message = 'Login error: ${result.errorMessage}';
        break;
    }

    setState(() {
      _title = Message;
    });
  }

  void _logout() async {
    await twitterLogin.logOut();

    setState(() {
      _title = 'Logged out.';
    });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          backgroundColor: const Color(0xFF167F67),
          title: Text('Twitter login sample'),
        ),
        body: Center(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              Text(_title),
              _title.isEmpty
                  ? ElevatedButton(
                child: Text('Log in'),
                onPressed: _login,
              )
                  : SizedBox(
                width: 0.0,
              ),
              _title.isNotEmpty?  ElevatedButton(
                child: Text('Log out'),
                onPressed: _logout,
              ):SizedBox(width: 0.0,),
            ],
          ),
        ),
      ),
    );
  }
}
