[ToniTornado]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

When I run the example application on macOS and perform a hot restart, I get the following exception:
[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(recreating_view, trying to create an already created view, view id: '0', null)

Expected Behavior

The widget tree is rebuilt and a fresh instance of InAppWebView is created without throwing an exception.

For unknown reasons, the Flutter PlatformView is not disposed automatically on Hot Restart.
It works as expected on Android, iOS, and Windows but not on macOS.
I think this has something to do with how Flutter manages the native PlatformView under the hood as this plugin is using the Flutter official API to render native views.
Probably, you should open an issue on the Flutter official repo and you can mention this issue.

Experiencing the same issue; wasn't aware it only happens on hot restart but a full rebuild helps

Here is the relevant issue in the Flutter repo: flutter/flutter#110381

A particular problem with using PlatformView and Hot Restart on macOS has been fixed. The fix is only on the main branch right now. I'm not entirely certain that fix will address this issue here, but it would be worth retesting against the Flutter main branch.
