如何在flutter WebView中打开app链接？

Question

在Flutter中，我使用Flutter webview插件启动一个url：

flutterWebviewPlugin.launch(url)

WebviewScaffold(
  url: url,
  appBar: new AppBar(title: Text(title), actions: [
    new IconButton(
      icon: const Icon(Icons.share),
      onPressed: () => Share.share(url),
    )
  ]),
  withZoom: true,
  withLocalStorage: true,
  withJavascript: true,
);

您可以在pub.dev包中使用webview_flutter

WebView(
        initialUrl: 'https://my.url.com',
        javascriptMode: JavascriptMode.unrestricted,
        navigationDelegate: (NavigationRequest request)
        {
          if (request.url.startsWith('https://my.redirect.url.com'))
          {
            print('blocking navigation to $request}');
            _launchURL('https://my.redirect.url.com');
            return NavigationDecision.prevent;
          }

          print('allowing navigation to $request');
          return NavigationDecision.navigate;
        },
      )

您可以在pub.dev包中使用url_launcher启动url

_launchURL(String url) async {
if (await canLaunch(url)) {
  await launch(url);
} else {
  throw 'Could not launch $url';
}}
