Flutter: jsonEncode for a List

Question

I am trying to jsonEncode a list in Flutter.

List<String> _list = ["name1", "name2"]

Things I tried:

jsonEncode(_list);
jsonEncode(_list.map((e) => e.toString()).toList());

This gives me a Json String however the data I get is:

"[\"name1\",\"name2\"]"

I want to send the data so that it shows:

{
  0: "name1",
  1: "name2"
}

PS: I am using Realtime Firebase Database for backend.

You can not have an Integer as a key in a valid Json Object. This is possible in JS, but not in the Json spec.
