flutter_webview_plugin: Choose File not working in Flutter WebView (working in Google Chrome)

Question

I am working with flutter_webview_plugin: ^0.4.0 and its working successfully but there is one issue that File Chooser is not opening.

I have to choose one file from WebView but its showing "No apps can perform this action."

I am using following code:

  @override
  Widget build(BuildContext context) {
    return SafeArea(
      child: _connectionStatus == ConnectivityResult.none
          ? Scaffold(body: NoInternetWidget())
          : WebviewScaffold(
              url: "https://app.capsavvycrm.com/admin",
              withZoom: true,
              primary: true,
              enableAppScheme: true,
              withLocalStorage: true,
              withLocalUrl: true,
              resizeToAvoidBottomInset: true,
              withOverviewMode: true,
             
              initialChild: Center(child: CircularProgressIndicator()),
              javascriptChannels: jsChannels,
              withJavascript: true,
              allowFileURLs: true,
            ),
    );
  }

Tested on:

Samsung Galaxy J8 9.0:

• Google Chrome : Working (Camera, Files),
• WebView : Working (Camera, Files)

Samsung C9 Pro 8.0.0:

• Google Chrome : Working,

• WebView : Not Working

I don't know why its happening. Anyone can help please?
