so, Grid is now deprecated. I thought I would try and embrace the new constraint layout API. One of my use cases of Grid is to dynamically create and remove rows based on user input. I tried to do the same thing with ConstraintRow and was successful. However, it get's really slow after a couple of new row additions. You can view the code here. compile using FB 3 B2. click on "make new row" button a couple of times and you'll see what I mean.
