It will work if you add Semantics.

 TextField(
          decoration: InputDecoration(
            suffixIcon: Semantics(
              textField: true,
              child: IconButton(
                onPressed: () {},
                icon: const Text('icon'),
              ),
            ),
          ),
        ),

Thanks for the report. Reproduced this issue on Android with TalkBack. On iOS with VoiceOver, the TextField is focusable and read as desired. Similar issue at https://github.com/flutter/flutter/issues/39918 which was fixed a long time ago.

Verified on the latest Flutter stable 3.22.3 and master 3.24.0-1.0.pre.197.
