Hi team, from our Firebase Crashlytics we always got issue about IllegalStateException from your plugin. I think this crash happen because your plugin send result.error more than one submitted.

Hi @kinex thanks for resolve this issue. But, when you will publish the new version with resolved this issue? I see your code fixed 6 days ago. But, I see in the last version is 9 months ago. For now, our team still use Flutter version under 3. So, please support under Flutter 3. Because I always found another plugin that only support Flutter 3 without concern backward version. Thanks.

Sorry for the delay. Fix is included in 2.3.1
