How to convert a List into a Map in Dart

Question

I looking for an on-the-shelf way to convert a List into a Map in Dart.

In python for example you can do:

l= [ (\'a\',(1,2)), (\'b\'         


        

Answer 1

You can use Map.fromIterable:

var result = Map.fromIterable(l, key: (v) => v[0], value: (v) => v[1]);

or collection-for (starting from Dart 2.3):

var result = { for (var v in l) v[0]: v[1] };
