Webview crashes on url change on iOS about flutter_webview_plugin HOT 13 CLOSED

closing because it's fixed.

from flutter_webview_plugin.

I also tried using evalJavascript to change the browser URL to the desired page and that causes it to crash as well.

from flutter_webview_plugin.

might be related to this #49

from flutter_webview_plugin.

I don't think it is since I'm using an https url.

from flutter_webview_plugin.

The only other thing that's weird about the urls involved is that there are two different top level domains involved. The last navigation goes from subdomain.a.com to subdomain.b.com.

FWIW I tried disabling the transport security as mentioned in #49's proposed workaround, but it didn't seem to help.

I'm having similar issues on url changing... Doesn't happen all the time. Maybe once every 3 or 4 times for example. Can't duplicate the issue on Android.
Note: Have just run a flutter upgrade and now cannot duplicate the issue on iOS... Something must have changed very recently as I did a flutter upgrade on the beta channel only 2 days ago...

from flutter_webview_plugin.

... spoke too soon... Just had a straight run with executing my app about ten times in a row with the error but its back... ;-(

It seems to be a stale issue - last update back around a month ago - has anyone found a solution or moved onto a different webview plugin maybe?

can you try with the last version 0.1.6 ?

from flutter_webview_plugin.

It is still crashing in 0.1.6. I am using https and the web content is as well. The last things logged are:

flutter: webview on state changed. Instance of 'WebViewStateChanged'
Unsupported value: <FlutterError: 0x1d4223fc0> of type FlutterError

Note that some URLs work but some don't. And it is only crashing on my iPhone (not on the simulator).

from flutter_webview_plugin.

I'm also running into this problem for iOS. It works fine for Android. Using 0.1.6

from flutter_webview_plugin.

Same issue with iOS webview in simulator.

On attempt to tap on a input field, where the webview would normally show the OSK, the webview immediately crashes ::
