Just some thoughts. To keep all the platform code similar, we should simulate the API of a platform channel, even though we don't actually need one.

in _invokeMethod

if (Platform.isWeb) {
    out = await FlutterBluePlusWeb.invokeMethod(method, arguments);
} else {
    out = await _methodChannel.invokeMethod(method, arguments);
}

in _initFlutterBluePlus

if (Platform.isWeb) {
    FlutterBluePlusWeb.setMethodCallHandler(_methodCallHandler);
} else {
    _methodChannel.setMethodCallHandler(_methodCallHandler);
}

I've started on web support: https://github.com/boskokg/flutter_blue_plus/compare/master...feature/web-bluetooth-support

I implemented startScan. It should be pretty straightforward to implement the rest, if someone wants to.

Hi @chipweinberger, thank you for your work on this package!

I hope you don't mind, I have implemented the web platform, based on your initial branch.

What is the recommended approach for testing the web implementation?

[chipweinberger]

thats awesome. No recommended approach. Just try to test everything :)

[chipweinberger]

your code looks good. I think stopScan should be a no-op, not unsupported.

also, please update the readme. etc.

Thank you for your feedback, I have refactored stopScan to be a no-op, and also updated the readme.

@tnc1997 recently created a PR for Web: https://github.com/chipweinberger/flutter_blue_plus/pull/964

However, FBP plans to remain Android/iOS/Mac only for the foreseeable future.

If you'd like to add web support, please do it via wrapper (example: https://pub.dev/packages/flutter_blue_plus_windows).

I'll keep this issue open until someone creates a wrapper for Web.
