I am getting the following error with the webview_flutter plugin. It happens only the first time the webview is launched and closed and only happens when you run the app on the physical device.
I am using: webview_flutter: ^1.0.3
[✓] Flutter (Channel stable, 1.22.2, ...)
Any clue on how I can go about fixing this? Thank you.
