Unable to perform google login in flutter

Question

When I use google login it was working fine but now it's giving this error.

Google Login is working fine in another mobile

  final googleUser = await GoogleSignIn().signIn();

   // Obtain the auth details from the request
   final googleAuth = await googleUser?.authentication;<=Error is on this line
