# JsonEncoder class final

This class converts JSON objects to strings.

Example:

    const JsonEncoder encoder = JsonEncoder();
    const data = {'text': 'foo', 'value': '2'};

    final String jsonString = encoder.convert(data);
    print(jsonString); // {"text":"foo","value":"2"}

Example of pretty-printed output:

    const JsonEncoder encoder = JsonEncoder.withIndent('  ');

    const data = {'text': 'foo', 'value': '2'};
    final String jsonString = encoder.convert(data);
    print(jsonString);
    // {
    //   "text": "foo",
    //   "value": "2"
    // }
