## Steps to Reproduce

<!-- Please include full steps to reproduce so that we can reproduce the problem. -->
This is an issue similar to #115158
1. Create a TextField with a labeltext, as demonstrated at https://api.flutter.dev/flutter/material/TextField-class.html. Example code is provided below.
2. Start VoiceOver on macOS
3. Navigate to the TextField and notice that the VoiceOver does not read the labeltext.

**Expected results:** 
The VoiceOver is supposed to read the labeltext. This works well on Windows using the Narrator.
<!-- what did you want to see? -->

**Actual results:**
The VoiceOver does not read the labeltext. <!-- what did you see? -->

<!--
      Please create a minimal reproducible sample that shows the problem
      and attach it below between the lines with the backticks.

      To create it you can use `flutter create bug` command and update the `main.dart` file.

      Alternatively, you can use https://dartpad.dev/
      which is capable of creating and running small Flutter apps.

      Without this we will unlikely be able to progress on the issue, and because of that
      we regretfully will have to close it.
