Use case

Is it possible to cache "initialURL" so that if there is no internet, InitialURL always opens the page from the local cache if the app has been opened at least once and the cache is not cleared.

Proposal

Caching the intialURL as well as follow up URL after the first-page load just like PWA insides flutter.

What was done

I just created a simple WebView flutter app and accessed PWA website all pages, closed the app, disconnected from the internet, opened the app again and voila got the error, the page is not available.

But it works fine in the mobile chrome browser, it loads all pages I accessed with my Internet on even after disconnecting from the internet.

But inside flutter webview app, I get an error, "This webpage is not available".

@rebootcode
maybe I didn't understand correctly, but
it seems to me that you want to cache for offline use a whole website
if so, I'm not sure it's realistic expectation

PWA has an offline store option and if flutter_webview can support PWA, It will be just a magical moment.

Due to Flutter's limitations on 3D, I also have a significant portion of the application in WebView, and PWA support for WebView would be very helpful. Since in our region, there are problems with the Internet coverage.

I see there's an open feature request to integrate PWA for webview_flutter plugin. Also see this comment on feasibility of this request implementation. Would you be okay to follow-up in that issue and close this one as duplicate ?
Thanks.

@darshankawar, I see the previous #30582 thread recommends downloading the PWA app inside flutter.
But I recommend instead of downloading another app, just supporting the "offline" or "page cache" features using serviceworker or something similar inside webview to let page accessible offline.

It sounds similar and the objective may sound similar, but the approach and requirement are strictly for "offline" based access using serviceworker cache or something similar.
Not sure, if merging both and closing this thread would be right.
