iOS Autofill "hide my email" does not work

[just-doit]

Steps to reproduce

1. Use provided sample code (or build a simple app with a TextField)
2. Run app
3. Tap on text field
4. Tap on "Hide My Email"
5. Create a new "Hide My Email" address (or use the existing)

Expected results

I expect the TextField to be filled with the created / selected email address.

Actual results

The TextField stays empty.

Code sample

Code sample

```dart import 'package:flutter/cupertino.dart'; import 'package:flutter/material.dart'; void main() { runApp(const MyApp()); } class MyApp extends StatelessWidget { const MyApp({super.key}); @override Widget build(BuildContext context) { return const MaterialApp( title: 'Test', home: DetailPage(), ); } } class DetailPage extends StatefulWidget { const DetailPage({super.key}); @override State createState() => _DetailPageState(); } class _DetailPageState extends State { final TextEditingController _emailController = TextEditingController(); @override void dispose() { _emailController.dispose(); super.dispose(); } @override Widget build(BuildContext context) { return Scaffold( body: SafeArea( child: Form( child: CupertinoFormSection.insetGrouped( header: const Text('EMAIL'), children: [ CupertinoTextFormFieldRow( controller: _emailController, prefix: Icon(CupertinoIcons.mail, color: CupertinoColors.label.resolveFrom(context)), keyboardType: TextInputType.emailAddress, autofillHints: const [AutofillHints.email], ) ], ), ), ), ); } } ```

Hi @just-doit Unfortunately, I don't have a device that subscribe to iCloud+ to have Hide My Email feature. From my understanding, the anonymous/generated account is not auto-filled when you tap again on the fields, correct?

Can you please check this behavior on iOS native TextField?

[just-doit]

Normally, you tap on “Hide My Email” and a sheet opens, which in my case shows that I have already generated an address for the app. I then tap on “Continue” so that the sheet disappears again. The email address should then be inserted into the text field.

In addition to the fact that no text appears in the text field, it is also noticeable that the text field no longer has focus (the cursor has disappeared), but the keyboard is still open. It seems the text field looses focus as soon as "Hide My Email" is selected.

See attached video (this is a native TextField):

Thank you for the demo video. But I'm confused since you mentioned it's on a native TextField and I see the issue also appeared, right?

[just-doit]

Sorry, I think I misunderstood you. I thought it was about the two flutter classes CupertinoTextFormFieldRow vs TextField. The source code says CupertinoTextFormFieldRow while for the video I used a TextField.

But you probably mean a SwiftUI TextField. I have tested this with the following code and it works as expected:

import SwiftUI

struct ContentView: View {
    @State var text: String = ""

    var body: some View {
        TextField("EMail", text: $text)
            .textContentType(.emailAddress)
    }
}

Thanks for confirming this. It makes sense now. Labeling this for further investigation.
