could we get this merged in and patch released? thank you for putting this together! i was literally about to open the same pr as i just implemented it myself before seeing this: https://github.com/willsmanley/mixpanel-flutter

[willsmanley]

also, for wasmgc support, could yall consider including this commit? https://github.com/mixpanel/mixpanel-flutter/pull/175/files

this just adds crossorigin to the CDN which allows for wasmgc usage

[martinloesethjensen]

Could also add section in CHANGELOG.md

[pedromassango]

Will get back to this today

Is there an estimate for when this will go into master? It's currently blocking us from deploying to web. Thanks!

Do you know how to point your pubspec version to a remote git ref? That might help unblock you while we're waiting

Tried pulling this PR and using it, but is throwing errors on initialization. The error says:

DartError: PlatformException(error, NoSuchMethodError: 'jsify'
Dynamic call of null.
Receiver: Instance of 'LinkedMap<Object?, Object?>'
Arguments: [], null, null)

This is happening when running Mixpanel.init() and is thrown from

 void initialize(MethodCall call) {
    Map<Object?, Object?> args = call.arguments as Map<Object?, Object?>;
    String token = args['token'] as String;
    Map<String, dynamic> config = args['config'];
    init(token, config?.jsify() ?? {});
  }

Using breakpoints I have verified that config is not empty. Not sure if anyone else has run into this but is there a known workaround?

Just looked at this I can't reproduce it, can you share a minimal reproducible code?
