List<object> to json flutter code example

Example 1: flutter json to list

List to JSON: 
_______________________________________________________________________________
List<String> fruits = ['Apple', 'Banana', 'Orange', 'Strawberry'];
String jsonFruits = jsonEncode(fruits);

________________________________________________________________________________
JSON to List:
________________________________________________________________________________
You need to convert each item individually

	var json = jsonEncode(jsonFruits.map((e) => e.toJson()).toList());

or pass an toEncodable function

	var json = jsonEncode(jsonFruits, toEncodable: (e) => e.toJsonAttr());

Example 2: dart list to json

import 'dart:convert';

main() {
  List<String> tags = ['tagA', 'tagB', 'tagC'];
  String jsonTags = jsonEncode(tags);
  print(jsonTags);      // ["tagA","tagB","tagC"]
}
