I don't care about Google's design or operating systems. I don't want Google designed controls on my operating systems. Just like the Electron stuff doesn't look good on Mac or Windows (or GTK for that matter), likewise Google designed widgets won't look native on Mac, Windows or iOS. If your next thought is "what about the Cupertino widgets," what about them? They will never look or feel fully like the native stuff. So why should we settle for that either?
I'm saying it's the same, and has the same issues as other, less desired frameworks. I was wondering why Flutter gets a free pass on the same issues and why people are so excited about it, since similar frameworks exist for 20+ years.
