MissingPluginException for plugins.flutter.io/firebase_livestream_ml_vision0 (Only iOS)

[prabel]

Hi,
I tried to use this example - but every time I receive this exception

The following MissingPluginException was thrown while activating platform stream on channel
plugins.flutter.io/firebase_livestream_ml_vision0:
MissingPluginException(No implementation found for method listen on channel
plugins.flutter.io/firebase_livestream_ml_vision0)
flutter:
When the exception was thrown, this was the stack:
#0      MethodChannel.invokeMethod (package:flutter/src/services/platform_channel.dart:314:7)
<asynchronous suspension>

Yes, I have seen this issue - in fact I'm facing it too; I'm working on a fix but I'm not getting anywhere with it yet. You're welcome to open a PR if you can figure out a fix.
