Is There a Requirement for Pattern Matching in Dart?

I really wish dart would have pattern matching and unions. That's my number one request too. Do you know a? There's the language isee for it on the dark darklin slash language repository. You'll find it all them. Have you ever used pader matching before? Yes, yes, i do. Is the most fantastic thing i've ever used in my life. I just don't know why other languages jus don't have it. Itsa result of type. Ta, it's fantastic. But at least i would much rather have a uncompilable code that i know won't run verses and thenh make it run than to not know what's going to work
