我使用Myslq1作为我的Mysql数据库的连接插件，但是连接看起来没有问题，为何没有数据返回呢？请高手帮忙看一下，谢谢。

import 'package:mysql1/mysql1.dart' as mysql;

Future Database() async {
var settings = mysql.ConnectionSettings(
host: '108...',
port: 3306,
user: 'root',
password: '*****',
useSSL: false,
useCompression: false,
// maxPacketSize: 10000000,
//characterSet: utf8,
timeout: const Duration(seconds: 5000),
db: 'testdb');
var conn = await mysql.MySqlConnection.connect(settings);

print(conn.toString());
var result = await conn.query("SELECT * FROM users LIMIT 100;");
//await conn.close();
if (result.isEmpty) {
print('No data');
} else {
print(result.toString());
}
await conn.close();
}

运行结果：
