错误
最后，我在自己的移动设备上运行了这个应用程序。我也遇到了同样的问题，你没有解决吗？@Maenalnasan实际上这不是任何软件包的错误，两个软件包都会抛出相同的错误。我在这里提出了一个问题，但他们的反应不是很好：（这可能会对你有所帮助。
Future userRegistration() async {
String name = nameController.text;
String email = emailController.text;
String password = passwordController.text;
var url = Uri.parse('http://pro-connect.infinityfreeapp.com/register_user.php');
var data = {'name': name, 'email': email, 'password': password};
final client = HttpClient();
final request = await client.postUrl(url);
request.headers.set(HttpHeaders.contentTypeHeader, "application/json;charset=UTF-8");
request.write(data);
final response = await request.close();
response.transform(utf8.decoder).listen((contents) {
print(contents);
});
}
