jsonEncode function Null safety

String jsonEncode (
  1. Object? object,
  2. {Object? toEncodable(
    1. Object? nonEncodable

Converts value to a JSON string.

If value contains objects that are not directly encodable to a JSON string (a value that is not a number, boolean, string, null, list or a map with string keys), the toEncodable function is used to convert it to an object that must be directly encodable.

If toEncodable is omitted, it defaults to a function that returns the result of calling .toJson() on the unencodable object.

Shorthand for json.encode. Useful if a local variable shadows the global json constant.


String jsonEncode(Object? object,
        {Object? toEncodable(Object? nonEncodable)?}) =>
    json.encode(object, toEncodable: toEncodable);
