progress indicator when web page loads

[Alex Kravets]

I am trying to implement progress indicator for reloading url using webview plugin. Here are parts of the code:

...

flutterWebviewPlugin.reloadUrl('file://${file.path}')

        .then((onValue) =>
          setState(() {
            _isLoading = false;
          })
 );
...

Widget build(BuildContext context){
   return new Scaffold(
      body: Container(
        child: _isLoading
        ? Center(
          child: CircularProgressIndicator(),
        )
        : WebviewScaffold(
            url: 'about:blank',
        ),
      ),

    );

  } 

Debugging starting with setState() propagates through setState() and calls build(), however new web page does not load. If I substitute  WebviewScaffold for Text() widget - I can see text loading. Why can't I see WebviewScaffold loaded?

Thanks,

Alex

I would use webview_flutter

Do you think it's a problem with plugin and not my use of Flutter UI?

I would switch, but webView_flutter doesn't support combo box selection in a web page, where as webview plugin does. When I select with webview_flutter nothing happens, but in plugin everything works fine.

Well, if you read the README it says not to use alongside other widgets. The Flutter teams webview_flutter can be used in the tree (and I do exactly what you want with it).
