If you have ever searched for open source keyboards, you might have come across OpenBoard. But that project hasn't seen development in more than an year. Thankfully, there is a fork of it that is being worked upon quite actively. It already supports autocorrect, glide typing, user-defined dictionaries, multilingual typing and now material you themeing as well.
And even with that.. I gave it a shot for a while... But unfortunately, it is nowhere near as good as Google's swipe/glide typing. I was constantly having to fix words or just not use the swipe typing at all.
