body: <p>So following this tutorial for a simple login UI in Flutter </p>
  
  <p><a href="https://medium.com/better-programming/simple-firebase-login-flow-in-flutter-6f44c2b5c58a" rel="nofollow noreferrer">https://medium.com/better-programming/simple-firebase-login-flow-in-flutter-6f44c2b5c58a</a></p>
  
  <p>Apparently this package in flutter isn't being imported correctly. The particular lines that are not working are these 3 lines of code</p>
  
  <pre><code>import 'package:provider/provider.dart';
  ChangeNotifierProvider&lt;AuthService&gt;( //TODO: authservices and provider pages
  future: Provider.of&lt;AuthService&gt;(context).getUser(),
  </code></pre>
  
  <p>I have been searching a bunch and tried reading the docs and couldn't get any easy answers, but anyway thank you to anyone who gets me the answer to this</p>
  
  <pre><code>import 'package:flutter/material.dart';
      import 'package:provider/provider.dart';
      import 'home_page.dart';
      import 'auth.dart';
      import 'login_page.dart';
  
  void main() =&gt; runApp(
    ChangeNotifierProvider&lt;AuthService&gt;( //TODO: authservices and provider pages
      child: MyApp(),
      builder: (BuildContext context) {
        return AuthService();
      },
    ),
  );
  
  class MyApp extends StatelessWidget {
    // This widget is the root of your application.
    @override
    Widget build(BuildContext context) {
      return MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(primarySwatch: Colors.blue),
        home: FutureBuilder(
          future: Provider.of&lt;AuthService&gt;(context).getUser(),
          builder: (context, AsyncSnapshot snapshot) {
            if (snapshot.connectionState == ConnectionState.done) {
              return snapshot.hasData ? HomePage() : LoginPage();
            } else {
              return Container(color: Colors.white);
            }
          },
        ),
      );
    }
  }

  # The following defines the version and build number for your application.
  # A version number is three numbers separated by dots, like 1.2.43
  # followed by an optional build number separated by a +.
  # Both the version and the builder number may be overridden in flutter
  # build by specifying --build-name and --build-number, respectively.
  # In Android, build-name is used as versionName while build-number used as versionCode.
  # Read more about Android versioning at https://developer.android.com/studio/publish/versioning
  # In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

    # To add assets to your application, add an assets section, like this:
    # assets:
    #  - images/a_dot_burr.jpeg

    # An image asset can refer to one or more resolution-specific "variants", see

    # https://flutter.dev/assets-and-images/#from-packages
  
    # To add custom fonts to your application, add a fonts section here,
    # in this "flutter" section. Each entry in this list should have a
    # "family" key with the font family name, and a "fonts" key with a
    # list giving the asset and other descriptors for the font. For
    # example:
    # fonts:
    #   - family: Schyler
    #     fonts:
    #       - asset: fonts/Schyler-Regular.ttf
