WASM compliant

Is this widget WASM compliant?
When I use this widget within a simple js_interop project, it seems to build and run.

However, when I use this plugin within a more complex project, I get a runtime error with a message like this:

UnimplementedError: cannot call build on the fascade implementation of WebViewX.
it mentions the test build, which is confusing since i did not run the test execution.

Very odd -- when I run my simple app flutterjsinterop using the python3 server.py script in the build/web folder it appears like this.

The green portion is the webviewxplus - because I set the background color in the html

but if I run from intellij and add to the run configuration:

--wasm

then this immediately appears when the browser opens:
