Dart  is a pretty nice language, and practically speaking I don&#x27;t think it&#x27;s &quot;weaker&quot; (optionally typed) system is a concern. The vast majority of Dart libraries are typed, giving you all of the benefits (compile time type checking, runtime type checks, intellisense, etc.)<p>Check out the flutter project (<a href="http:&#x2F;&#x2F;flutter.io" rel="nofollow">http:&#x2F;&#x2F;flutter.io</a>) for a hint of what Dart on Android and iOS looks like.
