Big turnoff with Dart is the lack of json (de) serialization -- kind of shocking to have to resort to source code generation libraries in a modern language.

Also, statement based instead of expression based, and not immutable by default are kind of a drag; not the end of the world but a bit unpleasant, IMO.

Serialization support is coming, probably this year. As for statements vs expressions, it does have some expressions such as if and for inside lists but changing it wholesale to an expression based language would be too much of a breaking change.

Serialization support has been coming for years, I lost patience.

Otherwise, yes, some support for expressions, some support for immutability, no support for optional semi-colons, no privacy modifiers so "_" littered everywhere.

I just found it to be an exceedingly ugly language when I used it a couple of years ago. Yes, some more pleasant modern functionality has been bolted on since then, but it's unfortunate that Dart was chosen as the backing language for Flutter, which is an awesome mobile framework.

I thought dart could natively deserialize via dart:convert? It just only decodes to lists and maps, you have to manually map into classes.
