Autofill password field not triggering on (Android devices) for Flutter

That is a great improvement, but in my app the username field is not detected. However when I click on the password field it is working already. Is there something wrong with my code or your implementation?

Here is my simplified dart code:

dart
TextFormField(
textInputAction: TextInputAction.next,
keyboardType: TextInputType.emailAddress,
autofillHints: const [AutofillHints.username, AutofillHints.email],
// ...
),
TextFormField(
obscureText: _isObscure,
textInputAction: TextInputAction.send,
keyboardType: TextInputType.visiblePassword,
autofillHints: const [AutofillHints.password],
// ...
)
