我正在使用 InAppWebView 插件中的 InAppBrowser 类在我的颤振应用程序中打开浏览器。

案例:我正在检查流中的网络,所以如果没有连接来隐藏浏览器,如果有继续浏览

问题:显示浏览器后,当我想隐藏它时不起作用

主要代码

StreamBuilder(
      stream: networkStatusStream(),
builder: (BuildContext context, snapshot) {

if ( snapshot.hasData) {
checkNetworkStatus(snapshot.data);
}

if(netState){
  browser.openUrl(url: url);

  return Container(color: clrGrey,);
}
else {
   browser.hide();
   return   OfflineScreen();

}},)

InAppBrowser 类

class MyInAppBrowser extends InAppBrowser {
  @override
  Future onBrowserCreated() async {
    print("\n\nBrowser Created!\n\n");
  }

  @override
  Future onLoadStart(url) async {
    print("\n\nStarted $url\n\n");
  }

  @override
  Future onLoadStop(url) async {
    print("\n\nStopped $url\n\n");
  }

  @override
  void onLoadError(url, code, message) {
    print("Can't load $url.. Error: $message");
  }

  @override
  void onProgressChanged(progress) {
    print("Progress: $progress");
  }

  @override
  void onExit() {
    print("\n\nBrowser closed!\n\n");
  }


  @override
  void onLoadResource(LoadedResource response) {
    print("Started at: " +
        response.startTime.toString() +
        "ms ---> duration: " +
        response.duration.toString() +
        "ms " +
        (response.url?.toString() ?? ''));
  }

  @override
  void onConsoleMessage(ConsoleMessage consoleMessage) {
    print("""
    console output:
      message: ${consoleMessage.message}
      messageLevel: ${consoleMessage.messageLevel.toValue()}
   """);
  }
} ```
