Flutter App crashes if I use web views.

[ritvij-saxena]

Hello,
I have a simple app, where I press the raised button, a web view should be displayed. The application crashes if I open the web view for the second time.
I have seen the same happen even if I use other packages.

Packages which I have used
webview_flutter
webview_flutter_plus
flutter_webview_plugin
flutter_inappwebview

I thought it was an issue with the package, hence I raised an issue on the package's GitHub page, however, I suspect it's not due to the package

The error message mentioned in flutter_webview_plugin Issues #796 is the same even if I use different packages.

Emulator Details:

Name: Pixel_2_API_28
CPU/ABI: Google Play Intel Atom (x86)
Target: google_apis_playstore [Google Play] (API level 28)
Skin: pixel_2
SD Card: 512M

Hi @ritvij-saxena,
Except webview_flutter, all the plugins you listed are 3rd party plugins.
If you are experiencing the crash with webview_flutter, please provide flutter doctor -v and a minimal complete reproducible code sample.
Thanks.

Hi @darshankawar

Code:

import 'package:flutter/material.dart';
import 'package:webview_flutter/webview_flutter.dart';


class PaymentMethodsPage extends StatefulWidget {
  @override
  _PaymentMethodsPageState createState() => _PaymentMethodsPageState();
}

class _PaymentMethodsPageState extends State<PaymentMethodsPage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
            iconTheme: IconThemeData(color: Colors.black),
            backgroundColor: Colors.orange,
            centerTitle: true,
            title: Text(
              'Payment Methods',
              style: TextStyle(color: Colors.black),
            )),
        body: Center(
          child: RaisedButton(
            child: Text('Open View'),
            onPressed: openWebView,
          ),
        ));
  }

  void openWebView() {
    Navigator.push(
        context, MaterialPageRoute(builder: (context) => WebUI()));
  }
}

class WebUI extends StatefulWidget {
  @override
  _WebUIState createState() => _WebUIState();
}

class _WebUIState extends State<WebUI> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
          iconTheme: IconThemeData(color: Colors.black),
          backgroundColor: Colors.orange,
          centerTitle: true,
          title: Text(
            'Stripe WebView',
            style: TextStyle(color: Colors.black),
          )),
      body: Center(
        child: Container(
            margin: const EdgeInsets.all(10.0),
            child: WebView(initialUrl:'www.google.com', javascriptMode: JavascriptMode.unrestricted)
        ),
      ),
    );
  }
}

Hi @ritvij-saxena,
I tried your code on latest Stable version (1.20.1) and didn't see any crash. I was able to see url launch properly.

I see that you have directly passed www.google.com due to which you may not be seeing the url launching properly. Try to add https:\\ in prefix and see if it resolves your issue.

I tested on Android 8.1.0 device.

Hi @darshankawar
the https:// prefix you mentioned works. However, it takes around a minute or so, to load, and it crashes if I try to use the keyboard to type with this message (below the screenshot)

1. Any suggestions for a builder (Future/Stream/Any) that could be used while the web view renders?
2. In the error messages, the message below was consistent.

Any particular thing, I should be looking out for?

[darshankawar]

Hi @ritvij-saxena,
I again tried by typing out in the webview and was able to see the search results properly without any crash.

Can you try to switch to latest master or stable to see if you experience same behavior ?

Also for # 1, you may try to show a loading indicator upon tapping open webview that'll indicate that it is loading.
For # 2, can you try the official webview plugin example to see if it still crashes ?

[ritvij-saxena]

Hi @darshankawar
Your suggestion worked. However, it does crash if I go back and try to open the web view page again.

#1 is there any stream or a future in webview using which I can show the page, something like (pseudocode)

 if web view screen not completely loaded
     show CircularProgressIndicator()
 else 
     show webview()

#2 The example did not crash. I noticed in example code the Scaffold body was using the Builder() widget. I used it too in my app and played around. Eventually, it crashed when I searched something(results were displayed), went back(to the button screen), and tapped on the button to go to the web view screen again [with the same micro dump error as mentioned above]

@override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
          iconTheme: IconThemeData(color: Colors.black),
          backgroundColor: Colors.orange,
          centerTitle: true,
          title: Text(
            'Stripe WebView',
            style: TextStyle(color: Colors.black),
          )),
      body: Center(
        child: Builder(builder: (BuildContext context)=>WebView(initialUrl: 'https://www.google.com',
          javascriptMode: JavascriptMode.unrestricted,
          onWebViewCreated: (WebViewController webViewController) {
            _controller.complete(webViewController);
          },
        ))

Hi @ritvij-saxena,
I tried to replicate again on emulatoer Pixel 2XL api 27 and was able to navigate back and forth properly without any issues.
Can you share what api version is your emulator ? and please try on another device to see if it's consistent crash or intermittent.
