在 webview flutter 中面临问题，在 3.0.0 版本中显示空白屏幕

Question

facing issue in review flutter showing the blank screen in 3.0.0 version and it's in ios enter image description here

Answer 1

I have the same issue on Android, with versions 3.0.0 and 2.4.0. So I tested downgrading back to 2.3.1, which is what we were using before, and explicitely selecting the hybrid composition mode, by adding:

    if (Platform.isAndroid) WebView.platform = SurfaceAndroidWebView();

in initState, as described in https://pub.dev/packages/webview_flutter/versions/2.3.1

The issue also occurs . So it's probably not specific to v3.0.0.

Another interesting observation: the issue remains present if we upgrade to 3.0.0, then downgrade back to 2.3.1 (removing the aforementioned code which explicitly activates hybrid composition), and cleanup the pub caches...

So it might be caused by a third-party dependency but I don't understand why cleaning up the dep cache doesn't fix the issue when reverting back from 3.0.0 to 2.3.1...

Answer 2

I am still facing this issue and I am facing it in ios not in android
