What is the best way to display Firebase errors to the user in Flutter?

The best way to display Firebase errors to the user in Flutter is by using informative and user-friendly messages. This can be achieved through Flutter's UI components like `SnackBar` for brief notifications or `AlertDialog` for more detailed explanations. Avoid showing raw error codes directly to the user; instead, translate them into understandable language, such as 'Invalid email or password.'
