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"
// }
