Hey guys, Samsung Galaxy J5 user on Android 9 show me the following crash in crashlytics when using this plugin. If you Google the issue, your find this issue, which says:

If you are a plugin author and are seeing (or getting reports of) this message, you should audit your code to make sure you are never calling a Result response method more than once. If you find that your logic is correct, and have multiple in-flight method channel requests at the same time, that would be where this issue would be relevant.

Thanks for your help!

I have never seen this issue. I made sure that result is not called more than once in every function

Can you reproduce it locally?

It seems to be happening a lot lately with several plugins.

Very weird. I haven't tried to reproduce it yet, but never saw it before either. I don't really think it's flutter, so the only possibility is result getting called twice?

I can't reproduce it locally.

It seems, from the logs, that it's caused when initializing:

Maybe It happened due to the ad. I use the device as a Firebase report but still can not reproduce it. Strange
