对话框内的Flutter WebView

Question

Widget webview() {
    return Container(
        child: Padding(
      padding: EdgeInsets.all(30.0),
      child: Row(
        // mainAxisAlignment: MainAxisAlignment.center,
        mainAxisAlignment: MainAxisAlignment.spaceEvenly,
        children: <Widget>[
          new GestureDetector(
            child: Text(
              'About',
              style: TextStyle(fontSize: 16.0, color: const Color(0XFF5867DD)),
            ),
            onTap: () {
              openWebview();
            },
          ),
        ],
      ),
    ));
  }
  Widget openWebview() {
    return Container(
      child: WebviewScaffold(
        url: "https:www.google.com/",
        withZoom: true,
        withLocalStorage: true,
      ),
    );
  }
}

我正在Flutter应用程序中创建Webview，问题是我想在单击textview时在对话框中打开Webview。

只需像

一样将其包装在MaterialPageRoute中

  Widget openWebview() {
        Navigator.of(context).push(new MaterialPageRoute<Null>(
            builder: (BuildContext context) {
return Container(
      child: WebviewScaffold(
        url: "https:www.google.com/",
        withZoom: true,
        withLocalStorage: true,
      ),
    );

            },
            fullscreenDialog: false
        ));
  }
