Is anyone know how to call JS function from dart ? I followed steps which linked below.
Firstly, appear this error.
"Error: Not found: 'dart:js' import 'dart:js';"
I followed previous answer which comment this line from js.dart and fixed it.
[export 'dart:js' show allowInterop, allowInteropCaptureThis;].
But now I got another error below.
No top-level method 'callJsFunc' declared. Receiver: top-level Tried calling: callJsFunc()
Is anyone know how to fix this error ?
I tried other Flutter SDK version (latest one and 3.0.5) but got same error.

flutter uses dart not javascript.
so... actually you require a separate javascript engine if you want to use javascript with flutter and that can be done with dart ffi unless you are building a web app with flutter.
However, there is a library called flutter_js and you can use it if you need to run javascript.
On the other hand, if you are interested in using embeddable Javascript engine with your flutter project by yourself.
you should check this link out where it shows how to use ffi for attaching an embeddable Javascript engine called Duktape

Thank you for the advice. I will try to use flutter_js package.
Our teams are developing iOS and Android used by Flutter. Flutter Web is not developing. Those dart:js, js|dart packages can be used for Flutter Web app only?
