code seems broken on latest flutter

[sivang]

dear Johannes, there is a bug in the code according to latest Flutter with the transformer:

I thought this was just a VSCode fluke, but that code fails to compile with that.

Can you suggest a fix?

Also, it seems documentation is poor when it comes transformers, if you could either link your tube about it or provide explanation here it would be rad :) Thank you for your nice tutorial!

A quick fix might be to write

final snaps = data.docs.map<Map<String,dynamic>>((doc) => doc.data()).toList();

Still gives this:

Could you perhaps paste the link to your youtube video about transformers perhaps in your very condensed closure style? prevalent documentation is very basic and does not at all discuss such advanced use cases..
