Create an alias for a Map specialization in Dart

Question

Ideally I'm looking for something like :

typedef Json = Map<String, dynamic>;

From what I understand, this language feature is under review typedef for simple type aliases with ETA Q1'19

But for a immediate alternative, what would be the simplest way to "extend" a Map in Dart ? All the solutions I could find are quite old and look overkill. At the end I just want an alias for my Map.

Thanks in advance.
