下面的代码 sn-p 在 Flutter json decode 中抛出 Format Exception，请问有什么建议吗？
import 'dart:async' show Future;
import 'dart:convert';
Future<String> readBooks() async {
String jsonString = '{"description":"As part of the "You Don’t Know JS" series","quantity":55}';
Map<String, dynamic> books = json.decode(jsonString);
return jsonString;
}
格式异常：
