Also it is very incomplete. For example there's no way to do custom widgets that draw text (e.g. a graph). There's no good text area widget (there is one but it is extremely limited - you couldn't use it for a log output for example).
Plain QtWidgets is way way better on every level except animation and styling. And maybe touch support.
But if I were making a mobile app I'd definitely use Flutter. Much nicer experience than QML.
