Can you just

import 'dart:convert';

then as an example:

var scores = [
  {'score': 40},
  {'score': 80},
  {'score': 100, 'overtime': true, 'special_guest': null}
];

var jsonText = jsonEncode(scores);
assert(jsonText ==
    '[{"score":40},{"score":80},'
        '{"score":100,"overtime":true,'
        '"special_guest":null}]');

quote from the document:

Only objects of type int, double, String, bool, null, List, or Map (with string keys) are directly encodable into JSON. List and Map objects are encoded recursively.

And check this link https://dart.dev/guides/libraries/library-tour#dartconvert---decoding-and-encoding-json-utf-8-and-more for more details.
