mongo_dart Dart的MongoDB驱动程序

Question

我只是尝试连接到我的MangoDB。来自flutter App ..，但出现错误

" SocketException: OS Error: Connection refused, errno = 111, address = 127.0.0.1, port = 46046 "

我的代码：-

import 'package:mongo_dart/mongo_dart.dart';

main() async {

Db db = new Db("mongodb://127.0.0.1:27017/chat");

await db.open();

print('''Hii ''');

await db.close();

print('closing db');
}

任何建议
