NOTE: This comment is auto-generated.

Are you sure you have already searched for the same problem?

Some people open new issues but they didn't search for something similar or for the same issue. Please, search for it using the GitHub issue search box or on the official inappwebview.dev website, or, also, using Google, StackOverflow, etc. before posting a new one. You may already find an answer to your problem!

If this is really a new issue, then thank you for raising it. I will investigate it and get back to you as soon as possible. Please, make sure you have given me as much context as possible! Also, if you didn't already, post a code example that can replicate this issue.

In the meantime, you can already search for some possible solutions online! Because this plugin uses native WebView, you can search online for the same issue adding android WebView [MY ERROR HERE] or ios WKWebView [MY ERROR HERE] keywords.

Following these steps can save you, me, and other people a lot of time, thanks!

@ayushkadbe my Problem was not related with the package. I made a rollback to the latest stable release (5.x.x). But the error was caused by an crash of my code in my application

For me - updating the index.html was necessary, make sure to add

<script type="application/javascript" src="/assets/packages/flutter_inappwebview/assets/web/web_support.js" defer></script>

to the web/index.html file (in the section).

If someone is still facing this issue and is depending on the version 6.0.0-beta.30 or later

Add this line in the head tag of your index.html

    <script

      src="/assets/packages/flutter_inappwebview_web/assets/web/web_support.js"

I get the same error on version 6.0.0 (and flutter_inappwebview_web 1.0.8), tried updating the index.html with the above script element, as the last part of the <head> element, and still get the same error.

I see three instances of web_support.js in my project's folder, all in the "build" folder, e.g. /build/flutter_assets/packages/flutter_inappwebview_web/assets/web/web_support.js

Any other ideas?

philvmx1 commented 3 months ago

Workaround if you're still having problems:

Remove defer from the script tag. If this loads after main.js you're still hosed. Let it parse inline so it can add the window.flutter_inappwebview object.

<script type="application/javascript"
src="/assets/packages/flutter_inappwebview_web/assets/web/web_support.js" ></script>

"If the defer attribute is set, it specifies that the script is downloaded in parallel to parsing the page, and executed after the page has finished parsing." (https://www.w3schools.com/tags/att_script_defer.asp)

Solution for the dev team: use some kind of event triggered by web_support.js script to set nativeCommunication rather than assuming window.flutter_inappwebview is already there.

tasibalint commented 2 months ago

I was looking for this for months... for me it worked well in debugger or on local flutter run -d edge.
BUT! on my server it didn't! why, because my https://server.com/web is the url for the default index, which nginx nincely forwards, but my index.html can not find <script type="application/javascript" src="/assets/packages/flutter_inappwebview_web/assets/web/web_support.js" ></script>
Solution:

  <!-- inAppWebView, for local web --->
<script type="application/javascript"
src="/assets/packages/flutter_inappwebview_web/assets/web/web_support.js" ></script>
  <!-- inAppWebView, for remote https://server.com/web --->
<script type="application/javascript"
src="/web/assets/packages/flutter_inappwebview_web/assets/web/web_support.js" ></script>

How I found this out: Under developertools/networkcalls looked for web_support.js which had a result of:

<meta http-equiv="refresh" content="0;url=https://server.com/web">

After fixing /web before the /assets it worked!
