Flutter Firebase_auth - Form Validation and Error Handling

We continue our Firebase_auth series by doing some preliminary form validation and Error Handling; making sure the login fields are populated and the right format as well as showing any errors that come directly from Firebase.

The Tutorial was soooo good man you are Live saver man I been serarching this type of video for three days

[gadgetologist]

First... I really like your videos and style. Very helpful! Your videos have helped me a great deal.
Second... There are a couple of issues in the code which are not huge, but...
Symptom: When the user types in an existing account with a password that doesn't meet the password requirements, the CircularProgressIndicator goes on for infinity, or at least until the user manages to get through the form validation and to the FirebaseAuth part.
Solution is the "setState(() => isLoading = false);" needs to go outside the if, down one line for both the "Sign Up" and "Sign In" section.
Thank you for your videos.

Bro one question in minute 5:06 after null what form is that? Thanks

Hey, not sure if you're still checking comments or if you'll see this one but I wanted to ask: I followed what you'd done so I could put the form validation and error catching into a project of mine, but the only issue is that the errors from Firebase only show up after the event happens when I save the file from inside my IDE whilst the app's running inside an emulator. Is there any way to fix this as yours looked instant on the video? Any help/guidance/advice you could provide would be much appreciated.

Thanks in advance.

Please consider doing a CRUD tutorial or a file upload on Flutter 2.0

If user submit the form without filling the inputs(invalid inputs), isLoading remains true because it's inside the if block that never runs without valid inputs.
