Unable to open pdf link in webview

@efortuna I am using this plugin webview_flutter to open a pdf link which works properly on iOS, but on Android, I am getting below error:

No DRP key due to exception:java.lang.ClassNotFoundException: com.android.webview.chromium.Drp

I am using Android emulator (Nexus 6P, OS: Marshmallow).

If I understand correctly, above error is related to runtime permissions being required on Android for api > = 23.
Would you know how to give required permissions to address this issue ? Or any workaround that'll help to open pdf using this plugin ?

This is how I am using the webview plugin as a sample:

class _MyHomePageState extends State<MyHomePage> {

  Completer<WebViewController> _controller = Completer<WebViewController>();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
          title: Text('WebView Demo')
      ),
      body: WebView(
        initialUrl: 'http://unec.edu.az/application/uploads/2014/12/pdf-sample.pdf',
        javascriptMode: JavascriptMode.unrestricted,
        onWebViewCreated: (WebViewController webViewController) {
          _controller.complete(webViewController);
        },
      ),
    );
  }
}

Hi,
The example is working great.

For Android, there's device navigate button, if I click on that back button, it go back to previous screen not navigate in the webview.
