Flutter app and not being able to pinpoint a button in the DOM or explorer/ Recorder

Why are some of the pages in my app just an entire View of a view? I.e. record functionality won’t record the step that I press any of these buttons. And I can’t find these buttons in the DOM. On other pages within the app I am however able to click buttons etc. Is it a rendering thing or what?
How am I able to automate in TestProject that a button is clicked in the example below?

Thanks in advance!
