@felangel Works great and turns out wasn't far away from what I had - I think moving things out to widgets (like you did) did the trick. Makes (seemingly) complex code more readable. Yeah, be great to have that as a recipe for others!

Then once the user has the basics (with your snippet), they can easily do more complex stuff like using a FutureBuilder for changing text/actions after a delay.
