title: missingpluginexception(no implementation found for method firebase#initializecore on channel plugins.flutter.io/firebase_core)
body: <p><strong>Error Description</strong>
  I am running my flutter app on windows desktop
  I am using master channel in android studio in order to run it on desktop.
  I have integrated firebase to my app, and login signup is working fine, but when I try to add or get data from my cloud firestore, the error appears to be is &quot; No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp() in Flutter and Firebase&quot; , which was solved by adding</p>
  <pre><code>void main()
  async
  {
     WidgetsFlutterBinding.ensureInitialized();
     await Firebase.initializeApp();
     // if (USE_FIRESTORE_EMULATOR) {
     //   FirebaseFirestore.instance.settings = Settings(
     //       host: 'localhost:8080', sslEnabled: false, persistenceEnabled: false);
     // }
    runApp(MyApp());
  }
  </code></pre>
  <p>to my app.
  but after adding this I got this error:</p>
  <pre><code>Launching lib\main.dart on Windows in debug mode...

  <p>and that's the error I am unable to solve. My app GUI does not show after this error.
  I have tried multiple solutions which were available on internet, but none of them worked for me.
  I have provided below flutter doctor and pubspec, kindly have look and help me solving this issue.
  Thanks in advance
