Hi,

Does this plugin provide serviceworker support for an offline cache of web-pages to view the pages offline from the cache?

Just like how PWA works for the web, Does Plugin support serviceworker.js file and load and store the pages from/on a cache?

Thanks

Hello @shah-xad, could you help me, I'm using

onWebViewCreated: (controller) {
                _controller = controller;
                _controller!
                    .loadUrl(Uri.dataFromString(_sharedState.message!.body!, mimeType: 'text/html', encoding: Encoding.getByName('utf-8')).toString());
              },

navigationDelegate: (request) async {
          final String? url = request.url;
          if (url != null && (url.startsWith('http') || url.startsWith('www'))) {
            UrlLaunchHelper.tryLaunch(url);
            return NavigationDecision.prevent;
          }
          return NavigationDecision.navigate;
        },

I use it in my project, there will be a crash problem, how to solve this problem?

import 'package:webview_flutter_plus/webview_flutter_plus.dart';

}

class _TopicWebTemplateViewState extends State<TopicWebTemplateView> {

       SizedBox(
         height: _height,
         child: WebViewPlus(
           onWebViewCreated: (controller) {
             this._controller = controller; // assets/html/test/index.html

           },
           // javascriptMode: JavascriptMode.unrestricted,
         ),
       )
     ],

I can't load the local html file when there is a space in its name (assets/file/test 1.html); tested with no sapces and it's working.
ps: I can't remove the spaces, I have 100s of files, and I need to keep the name like that.

            },
            javascriptMode: JavascriptMode.unrestricted,
          ),
        );

The widget.articleModel.body does not contain any html or body tags, it's just paragraph tags

I'm loading html file locally, it contain large image and can't fit on device width, so I need the webview to scroll horizontally, is it possible?

I have added flutter_html 2.0.0 to my project which displays blog content. Tweets and other embedded posts are not rendering properly. I think there is no javascript support and because of that, the rendering is not working.

Can anyone please help me out with this?

Thanks in advance 😊

the app is force close when rendering larger html data

the getHeight calculation appears to ignore the height of the loading image within the html content. In particular on iOS devices.

I'm trying to use the webviewplus to display the html content of several community posts on the same page, but some are cut short while others are much longer than needed for the content.

I use webview to show html content received through API and it works great.

However I have an issue, when I increase font size in the device settings web view font is increased, is there any way to prevent this. We have font size set in css that is also sent from the backend and I would like font size to be fully controlled by CSS.

Thanks!

Please integrate your source code with solution mentioned at https://crizantlai.medium.com/flutter-how-to-make-webview-transparent-9e3ce25d8d0

Hello,

Thank you for this package. I can not figure out why the URL I passed lead to a blanc page and throw the following error:
Unable to load asset: https://www.servicesadom.com/index.html

When I try my URL in a regular browser, it works well.
The website I am trying to display has been made in Flutter too. This might be linked to the issue, I guess...

Here is the URL I am using: https://www.servicesadom.com/#/

Any idea ?
Many thanks,
Benjamin

I have an html page that has some inputs that open a numeric keyboard. The problem is that they show up for like half a second and then an alpha numerical keyboard shows up. How to solve this issue? I really need that numeric keyboard. I'm using an Html file from my assets.

I have some URLs inside a webview in a listview and when users click on any URL, I want it to be opened inside a browser rather opening inside the webview. Is it possible? Could you please tell me how can I achieve this?

I download the html file and its zip, and unzip it to a folder in local temporary directory, it includes all the CSS and scripts,and also some assets like videos and images in local. I could get the index.html file path, and could run the index.html in local chrome, but how could I use webview_flutter_plus to load the index.html from local disk?

Your library is dependent on WebView_Flutter with the latest being webview_flutter: ^4.4.2, there is a non-exhaustive change to the API. [WEBVIEW](WebView Flutter).

Kindly update to the latest API changes with deprecated note [showing workings] for guidance to enable users of your package enjoy the latest version of WebView-Flutter as we currently stuck with the old version.

Hi im trying to integrate Formio using my webview_flutter_plus.

Hello,

I am using your package to display an html content from my assets. It works great but the default size it a bit too small and does not uses all the width of the screen.
Is there some adjustments I can do to better fit with my screen?

Thank you,
Benjamin.

What about web?

like: https://pub.dev/packages/webviewx

What I intend to do:
I installed threejs from npm and then loading the local min script package to the html and it shows this error.

• package gets loaded and is working fine on vscode live server and static html, but not on the webview widget in the flutter app

What the error is:

I/chromium( 9481): [INFO:CONSOLE(0)] "Refused to execute script from 'http://localhost:39875/node_modules/three/build/three.min.js' because its MIME type ('text/plain') is not executable, and strict MIME type checking is enabled.", source: http://localhost:39875/sketch.html (0)

Other things I did:

• I tried 'imports', type="module", type="text/javascript", changing file structure with no luck and the same error is shown.

Temporary solution:

• My work around for this at the moment is copying everything from the min script and pasting it inside the html script tag and it works as expected. But this makes my html file very large and inconvenient.

Here is a snippet of what I'm trying to do.

sketch.html

<!DOCTYPE html>
<head>
    <meta charset='utf-8' />
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
</head>
<body></body>
<script src="./node_modules/three/build/three.min.js"></script>
</html>

sketch.dart

import 'dart:io';
import 'package:flutter/material.dart';
import 'package:webview_flutter_plus/webview_flutter_plus.dart';

class Sketch extends StatefulWidget {
  const Sketch({super.key});

  @override
  State<Sketch> createState() => _SketchState();
}

class _SketchState extends State<Sketch> {
  @override
  void initState() {
    if (Platform.isAndroid) {
      WebViewPlus.platform = SurfaceAndroidWebView();
    }
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return const WebViewPlus(
      initialUrl: 'sketch.html',
      javascriptMode: JavascriptMode.unrestricted,
    );
  }
}

This was the error:
Unsupported operation: Trying to use the default webview implementation for TargetPlatform.windows but there isn't a default one

This project was working fine 2 months ago... now I returned to this project... and seeing this error...

when I load local html which is built by vue-cli, but i got an error:

Refused to execute http://localhost:52746/assets/dist/js/app.f3d1d93c.js as script because "X-Content-Type-Options: nosniff" was given and its Content-Type is not a script MIME type.

How can I fix it? Is it useful to set headers of arguments?
