webview_flutter просто показать пустой экран в эмуляторе android

1 голос
/ 07 апреля 2020

После установки webview_flutter 0.3.19 + 9 библиотека в моем более плоском проекте, я хочу использовать ее, чтобы написать код: 

import 'dart:async';

import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';

class ConfigWebViewScreen extends StatelessWidget {
  ConfigWebViewScreen(this._result);
  final dynamic _result;
  Completer<WebViewController> _controller = Completer<WebViewController>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: SafeArea(
        child: WebView(
          initialUrl: "https://mc.iotel.ir/",
          javascriptMode: JavascriptMode.unrestricted,
          onWebViewCreated: (WebViewController webViewController) {
            _controller.complete(webViewController);
          },
        ),
      ),
    );
  }
}

, но отметка отмечена на мой android эмулятор ?? отображается другой URL-адрес, такой как https://stackoverflow.com/, и веб-представление работает, но не может отображаться https://mc.iotel.ir/?
