json top-level constant Null safety

JsonCodec const json

An instance of the default implementation of the JsonCodec.

This instance provides a convenient access to the most common JSON use cases.


var encoded = json.encode([1, 2, { "a": null }]);
var decoded = json.decode('["foo", { "bar": 499 }]');

The top-level jsonEncode and jsonDecode functions may be used instead if a local variable shadows the json constant.


const JsonCodec json = JsonCodec();
