Needs Update
Is there an existing issue for this?
Use case
I would like to be able to use SelectableArea to layout my fixed position text, however, I still need to gather the Rects from the text to run my custom highlighting code.
Proposal
I would appreciate it if 'Selectable' were to offer getBoxesForSelection (TextSelection). After a preliminary search of the source code, it would seem as though all of the different pieces of data is there, it would be a matter of tying it all the pieces together in order to cleanly return the Rects from a given TextSelection. I'd be willing to work on this as well, but I would need a little direction and recommendation on where to start. My current issue is I'm unsure in the SelectableRegion/Area exists the ability to look through all the children who are Selectable.
