如何在flutter中绕过SSL证书验证？

import 'dart:io';

HttpClient createHttpClient() {
  HttpClient httpClient = new HttpClient();
  // 禁用SSL证书验证
  httpClient.badCertificateCallback =
      (X509Certificate cert, String host, int port) => true;
  return httpClient;
}

void sendRequest() async {
  HttpClient httpClient = createHttpClient();
  HttpClientRequest request = await httpClient.getUrl(Uri.parse('https://example.com'));
  // 禁用SSL证书验证
  request.badCertificateCallback =
      (X509Certificate cert, String host, int port) => true;
  HttpClientResponse response = await request.close();
  // 处理响应
  await response.transform(utf8.decoder).forEach(print);
  httpClient.close();
}
