I solved it by cloning the demo and including the folder ‘www’ from the demo into my App, then modify the ‘www/index.js’ to my liking(am using leafletjs for my Map, so I get events from the map and to the map from {N}) hope it helps

Hello. I have the same issue on iOS device. It fails because the javascript local file cannot be loaded. I have followed the solution in this comment and it works. https://github.com/NativeScript/NativeScript/issues/6377#issuecomment-433322681

Nothing Work for me this error comes once in a while

[devyaz]

hi, you need nativescript-webview-interface in your www folder or just clone it and use the www folder in your app or clone my repo Nativescript-Leaflet-Map as a working example you need a Mapbox Mapbox signup access token insert it into the index.html file

@devyaz , does the HTML file needs to be available locally?

[devyaz]

yes it has, i didn't test hosted file, but i believe it should work

@devyaz , BTW, the plugin does not work on iOS (no logs in the console at all) and on Android, passing data from webview to nativeapp works but not when passing data from nativeapp to webview and showing this error.

Uncaught TypeError: Cannot read property '_onNativeEvent' of undefined

Note: I'm trying to load a hosted page and not a local file.

[kriefsacha]

Someone got news from that ?

[rpragesh]

@ejlocop did you find the solution???

[devyaz]

I did back then, but thanks to webpack it doesn't work any more, I've switched to Flutter now trying flutter_webview_plus but I can't get leaflet map to render with local assets, only hosted

This was the way I solved it out

[baysoft]

It's a race condition problem. I solve it using a 300ms delay like this:

    setTimeout(function () {
      oWebViewInterface.emit("from-native", { data: "testing" });
    }, 300);

I'm using the latest {N} and android 12.
