Have you already searched for a solution? I also encountered the same problem, which is restoring a white screen after the application enters the background, even if I listen for page recovery events and reload, there will still be issues.

Me too, I don't know when I can fix this bug

[LarssK-TS]

Do you have the same issue with the fork zikzak_inappwebview package?

l don't know this package

[LarssK-TS]

I moved to it as this package feels like it has been abandoned.

Are you okay? Does this bug affect real business scenarios? Is there any compatibility solution to solve this problem that can be shared?

At present, only a button that can be turned off is provided to users to prevent the screen from completely freezing due to white screen. It seems that this is all we can do

I have found that there is a similar problem in Chrome browser, which will reload the page. However, I have not yet found that this library provides a corresponding hook function and cannot listen for the corresponding state. In addition, I have seen someone say that they call the load method, but it still has a white screen

                            initialSettings: InAppWebViewSettings(
                                 useShouldOverrideUrlLoading: true, // <-- Try removing this line
                                 saveFormData: false,
                                 useHybridComposition: true,
                                 clearCache: true,
                                 cacheEnabled: false,
                                 cacheMode: CacheMode.LOAD_NO_CACHE,
                                 allowBackgroundAudioPlaying: true,
                             )

Have you tried removing useShouldOverrideUrlLoading?
For me this param stopped JS from fully loading so in my case Google maps wouldn't display markers.

This might be helpful if you really need it #146

no, you can see my Behavior, it's not stopped code , the page is loaded, back to desktop or other app, After a period of time, when I reopened it, I found that the webpage turned white, and error stack is empty, dont't know what happened

[Matey2010]

Had same issue but looks like removing useShouldOverrideUrlLoading fixes it. Thanks @LarssK-TS
