I am conflicted about Flutter. Is it worth learning, over, say Angular (for web) or Xamarin (for mobile and cross platform stuff)?<p>Flutter for web was just released after a long time in beta stage. It looks like a good language and framework, but I don't see many options for customization. And frankly, the UI composition syntax is tasteless, in my view (Compared to React, which is awesome, or Angular, which is verbose and complex but still understandable)
