Hi @ethanblake4 and @cuifengcn,

I would love to work on this issue. Can you elaborate more on what it entails?

ethanblake4 commented 1 year ago

@DeleMike Sure, this is a great place to start on dart_eval as it just involves making standard library bindings. I'd recommend reviewing this PR to see an example of some functions that were added to List and Iterable. In this case you'd be adding the function containsKey to $Map in map.dart.

Released in v0.7.2
