Description

I wrote the example. https://pub.dartlang.org/packages/flutter_webview_plugin#-example-tab-

I pushed "Open widget webview" button. The example show log text onStateChanged: WebViewState.startLoad and onStateChanged: WebViewState.finishLoad in the bottom.

I pushed "Open widget webview" button again, but it didn't show log text again. Why only once?

I just want to do is that call JS when WebviewScaffold's url finish.

Research direction
Investigate the flutter webview plugin source code, specifically the WebViewState listener implementation. Look for whether the listener is unregistered after the first callback or if the example code needs to re register the listener. Check the comments on the issue for any clues or suggested fixes.
