title: MissingPluginException exception when a firebase anonymous sign-in with flutter (windows) app
body: <p>I recently started out with flutter for windows. I'm following <a href="https://www.youtube.com/playlist?list=PL4cUxeGkcC9j--TKIdkb3ISfRbJeJYQwC" rel="noreferrer">this</a> firebase and flutter tutorial. At lecture 4, I am getting error with Firebase Auth:</p>
  <blockquote>
  <p>flutter: MissingPluginException(No implementation found for method signInAnonymously on channel plugins.flutter.io/firebase_auth)</p>
  </blockquote>
  <p>I think the problem is because I am building for windows. I don't know how to add firebase to windows application. Any help is appreciated</p>
  <p>Here is the complete log:</p>
  <pre><code>Launching lib\main.dart on Windows in debug mode...
  Building Windows application...
  Waiting for Windows to report its views...
  Debug service listening on ws://127.0.0.1:60688/97Ok8iT1Hjo=/ws
  Syncing files to device Windows...
  flutter: MissingPluginException(No implementation found for method signInAnonymously on channel plugins.flutter.io/firebase_auth)
  flutter: error signing in
  </code></pre>
  <p><em><strong>EDIT 1</strong></em></p>
  <p>pubspec.yaml file (dependencies section)</p>
  <pre><code>dependencies:
    flutter:
      sdk: flutter
    firebase_auth: ^0.14.0+5
    cloud_firestore: ^0.12.9+4
  </code></pre>
  <p><em><strong>EDIT 2</strong></em></p>
  <p>I updated the dependencies to use following versions:</p>
  <pre><code>  firebase_auth: ^0.18.1+2
    cloud_firestore: ^0.14.1+3
    firebase_core: ^0.5.0+1
  </code></pre>
  <p>But now I am getting the following error:</p>
  <pre><code>[ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: MissingPluginException(No implementation found for method Firebase#initializeCore on channel plugins.flutter.io/firebase_core)
  </code></pre>
  <p>This is what my main function looks like:</p>
  <pre><code>void main() async {
    WidgetsFlutterBinding.ensureInitialized();
    await Firebase.initializeApp();
    runApp(MyApp());
  }
  </code></pre>
