CMP WebView to Web Communication

[khalid64927]

Hi,

This is possibly a feature request. I have a use case where I need to send some json data to webpage being loaded in WebView Composable and possible handle some events coming from loaded web page. There has to be a two way communication between Mobile Platform WebView and Web Platform.

In iOS/Android Native I can achieve this with JavaScript injection.

I was wondering if there is any API available in this library for that.

[App.kt]
val state = rememberWebViewStateWithHTMLFile("index.html")
val jsBridge = rememberWebViewJsBridge()
val navi = rememberWebViewNavigator()

WebView(
state,
webViewJsBridge = jsBridge,
navigator = navi
)

navi.evaluateJavaScript("gogo('from kot')", { msg ->
println(msg)
})

[index.html]

<script> function gogo(msg, cb) { alert(msg) cb('from js') } </script>

[Conclusion]
Error Message: Uncaught ReferenceError: gogo is not defined
Unfortunately, it didn't work for me, so I reverted back to the native webview.
