Well, I'm yet to see a fast block editor implemented in Flutter (with proper RAM use as well). Another one is Super Editor[1] which is the editor from the Superlist app[2]. I didn't properly test it cause there are no builds. But the web version[3] hangs when I try to paste the text of War and Peace. I would like to test it properly one day.
