• I have searched for answers to my question both in the issues and in previous discussions.

• Did you import the GoogleOAuthProvider class? If not, then do from flet.auth.providers.google_oauth_provider import GoogleOAuthProvider
• Also, you'd need to invoke self.page.login(self.provider) to start the authorization flow.

You shouldn't be getting a NameError if you've imported it properly and that it is available in that scope.
