Thank You, needed this

[charafau]

Thanks for PR, give me some time to review this. Just looking at title of this - #457 what's difference between the two ?

[rinlv]

@charafau This #457 use fixed channel 'Android' to listen to JS function for Android version, my solutions help using the dynamic channel for both Android and iOS. More, I'm following this webview_flutter to make this PR. It's mean just call
Channel.postMessage(data) to listen to JS function for both Android and iOS, not complicated like this example of #457

@rinlv I've made a few changes to the dart part, namely adding the whole Javascript channel abstraction, which removes the need to do a switch on the channel for example when a message is received. I've made a pull request on your repo here

I will make review and check code on Monday 👍

[charafau]

Thanks for PR! I made some comments, but didnt compile that code yet. Code looks good though, will check tomorrow if it works as expected.
