Hi @Parth Bhanderi , it seems like you're encountering an error related to the OAuth2 token response from Microsoft. The error message indicates that public clients can't send a client secret [VERBOSE-2:dart_vm_initializer.cc(41)].
To resolve this issue, you should ensure that you're not sending a client secret when making the OAuth2 request. Double-check your configuration and make sure that you're not including a client secret in the request. If you're using the firebase_auth package, ensure that you've followed the official documentation correctly and haven't accidentally included a client secret in your configuration.
Please let me know if you have any questions and I can help you further.
