Firebase connexion avec AngularDart dans le navigateur Chrome

Question

Je suis en train de tester une application Web de connexion firebase avec DART angulaire dans le navigateur Chrome à localhost, mais en cliquant sur le sign-in la fenêtre de connexion a disparu en 1 sec et ne résulte pas avec succès s'identifier. En le testant sur Chromium, ça marche. Quelqu'un peut-il dire que dois-je faire pour résoudre ce problème?

    fb.GoogleAuthProvider _fbGoogleAuthProvider; 

    FirebaseService() { 
    fb.initializeApp(
     apiKey: "AIzaSyBOShlCgUeqTL99n32bjWdNlkH1RPk9Xx4",
