Accessibility TalkBack Android

I’m wondering if anybody has use TalkBack for a project and use accessibility advice like android:contentDescription and orther alternative contents that can be add to Image or TextField.
It’s that possible with Haxe or OpenFL ?

I think it would have to be an Android UI-based application to integrate with Talkback, unless there’s a way with a native extension?

I took a chance with native extension and it’s seems good for Android. But with IOS it’s seems more tricky…
Thanks for your advice.
