New post on /r/flutterdev subreddit: Are there any good (and maintained!) UI kits for Flutter? Hi there! While I love flutter and am I long term user, the value of UI kits to me are so, so valuable and allow me to work 10x faster. Are there any really great UI kits for flutter?Buttons, cards, etc. all the basics should be included. I know that material UI is a UI kit in itself, but I really don’t like how material UI looks and would rather use something else.Free or paid. Thanks!

New post on /r/flutterdev subreddit: How many isolates do you use? I've been programming my app for two years and it now has 30k lines without autogenerated code (80k with autogenerated code) and so far I haven't used isolates. Now I am in the process of implementing my first isolate to offer TTS to my users.So I was wondering, how many isolates do you use and how many lines of code do you have? Have you encountered any limitations with too many isolates? What do you use an isolate for?I think I have overlooked the isolate option too often and the isolate usage should be more of a standard rather than the exception.I counted the lines of code with:

find . -name '*.dart' | xargs wc -l

New post on /r/flutterdev subreddit: Riverpod: a better state management solution than bloc? I took a break from flutter for a few months and now everywhere I see, everyone is talking about riverpod. My go to state management solution was flutter_bloc (unless the app is just a couple of screens) but from what I am reading, Riverpod seems to be just as good as bloc if not better. How has your experience been with riverpod - particularly in medium/large projects? Is it really as robust and good as bloc or is it just the hype?
