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());
