我正在寻找一个简单的Flutter的例子，一个提升的按钮（onPressed）http请求打开硬编码的网址。我不需要响应。我不需要浏览器窗口出现。目标操作系统是Android。提前感谢。UPD：我不需要任何输出。只需要打开如https://autoremotejoaomgcd.appspot.com/sendmessage?key=SECRET_KEY&message=test的网址触发任务（安卓应用程序）任务。
溶液：

import 'package:http/http.dart' as http;
The button:
Expanded(child: ElevatedButton(child: const Text('Flashlight on'), onPressed: () {const url = 'https://autoremotejoaomgcd.appspot.com/sendmessage?key=SECRET_KEY&message=flashlight%20on';_launchHTTP(url);},),)

The function:    
void _launchHTTP(String url) async {
var response = await http.get(Uri.parse(url));
print('Response status: ${response.statusCode}');
print('Response body: ${response.body}');
}
