I am trying to use SpellOutStringAttribute to spell out the attributedLabel, but it just doesn’t spell it.

The documentation says:
/// A string attribute that causes the assistive technologies, e.g. VoiceOver,
/// to spell out the string character by character.

I am using a physical Android device with TalkBack to try it.

I couldn’t find a working example.

Semantics(
                    attributedLabel: AttributedString(
                      'something',
                      attributes: <SpellOutStringAttribute>[
                        SpellOutStringAttribute(
                          range: const TextRange(
                            start: 0,
                            end: 4,
                          ),
                        ),
                      ],
                    ),
                    child: Container(
                      color: Colors.$red,
                      height: 200,
                      width: 200,
                    ),
                  ),
