signInOAuth method
Starts a OAuth sign-in flow for provider
using Firebase.
The instance of FirebaseAuth will be from the default Firebase App
Unless withApp is used to build an instance
It will return authentication result OAuthCredential
.
If supported by Firebase, this will contains the provider access
token as accessToken
.
Implementation
Future<OAuthCredential> signInOAuth(String provider, List<String> scopes,
[Map<String, String>? customOAuthParameters]) async {
throw UnimplementedError("signInOAuth() is not implemented");
}
