Flutter autofill password with 1password not working for Android devices

Question

AutofillGroup(
      child: Column(children: [
        AutofillGroup(
            child: Column(
          children: [
            TextField(autofillHints: [
              AutofillHints.username,
            ]),
            TextField(autofillHints: [
              AutofillHints.password,
            ]),
          ],
        )),
      ]),
    );

With Google password manager it's working good, but not with 1password.

If email textfield pressed it's showing the 1password prompt but password never autofill. If password textfield is pressed the 1pass prompt not showing.
