Using with a tablet?

I dont think I can search this forum (sadly).

I have a lengthy drive in a week or two -- I'd love my child to be able to watch shows in the car while driving.

Is there a way to use a firestick with a tablet? Failing that - is there a good player that works on a tablet, where you can enter your info and be able to use it?

I'm sure I'm not the first to want to do this -- but, that doesn't mean it's possible :)
