Yes, It is a Map<String, List> as you said.
A visit from the book Flutter Proyects 👍
I don't quite understand the reason why the author chose to represent this data this way, whereas a List<List<double>> is much more direct, and doesn't force us to perform a temporary conversion to (and from) string in the method.
I suppose the intent was to make the code more explicit and easy to read, but it's kind of clumsy.
Thank you. Great Work!!
wow

Q/ What is the type of this variable?
is it the same as Map<String, List> or another thing?
