解决方案

添加此最新答案，因为现在有一个

因为软件包实际上在Android和iOS上使用本机Facebook登录SDK，所以这是现在要走的路。因此，没有借口使用Firebase或与自己进行交互！

希望它可以帮助遇到Facebook登录问题的其他人。并感谢包创建者 roughike

google signin使用 google_sign_in ，该软件包实际上已经相当成熟并且更容易开始。

解决方案

Adding this late answer since now there is a package, flutter_facebook_login that replaces flutter_facebook_connect. Here is a functioning main.dart example that should work. Just keep in mind you must have followed all configuration as described in the repository and must have a facebook app configured:

import 'package:flutter/material.dart';
import 'package:flutter_facebook_login/flutter_facebook_login.dart';
import 'dart:async';

void main() => runApp(new MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Flutter Facebook Login',
      theme: new ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: new MyHomePage(title: 'Flutter Login Facebook'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);

  final String title;

  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {    
  login() async {
    final facebookLogin = new FacebookLogin();
    final result = await facebookLogin.logIn(['email']);
   // final result = await facebookLogin.logInWithReadPermissions(['email']); --> Versions bellow 3.0
    switch (result.status) {
      case FacebookLoginStatus.loggedIn:
        print(result.accessToken.token);
        break;
      case FacebookLoginStatus.cancelledByUser:
        print('CANCELED BY USER');
        break;
      case FacebookLoginStatus.error:
        print(result.errorMessage);
        break;
    }
  }

  @override
  Widget build(BuildContext context) {
    return new Scaffold(
      appBar: new AppBar(
        title: new Text(widget.title),
      ),
      floatingActionButton: new FloatingActionButton(
        onPressed: login,
        tooltip: 'Login With Facebook',
        child: new Icon(Icons.add),
      ),
    );
  }
}

You should see the login screen when clicking bottom right button, and check the printed response on your debug console:

This is the way to go right now since the package actually uses native Facebook Login SDKs on Android and iOS. So no excuse to use Firebase or having to interface yourself!

Hope it helps others who are having troubles with facebook login. And credits go to the package creator roughike

For google signin use google_sign_in, this package is actually quite mature and easier to get going.
