Labels: a: text input,platform-ios,framework,a: accessibility,has reproducible steps,P2,team-design,triaged-design,found in release: 3.13,found in release: 3.14

### Is there an existing issue for this?

- [X] I have searched the [existing issues](https://github.com/flutter/flutter/issues)
- [X] I have read the [guide to filing a bug](https://flutter.dev/docs/resources/bug-reports)

### Steps to reproduce

1. Use the code sample provided in a `main.dart` file.
2. Run it in a iOS device (Android does not have this issue).
3. Enable `VoiceOver`.
4. Select the first `TextField`.
5. Press `next` on the virtual keyboard.

### Expected results

The second `TextField` is focused and VoiceOver reads its semantics.

### Actual results

The second `TextField` is focused but VoiceOver didn't read its semantics.
