i managed to get to a point where i dont get the error, for some reason when i removed flutter_downloader: ^1.1.7 from pubspec.ymal (update to ^1.1.7 did not helped)
but when i put the app in the background and i am getting a push notification, the onBackgroundMessage handler is not invoke
can some please explain (due to no documentation), when does the onBackgroundMessage handler supposed to be fire ?

@YonatanAmitzur
can anyone please edit this issue to make sure it doesn't reference any issue and pull request in this site??
for example: format it as code:
insert the hole stack trace into ``` ``` or select it and click the insert code button.

I'm using Flutter and I'm looking at the "[ZeroHung]zrhung_get_config: Get config failed for wp[0x0008]" that @YonatanAmitzur is having too at the start of the error log, same to other people and is nice to notice that the device used has the ID: COR L29 that's an Honor Play phone and the device that I'm having issues with has the ID: SNE LX3 and is a Huawei Mate 20. The issues look like is device related to this Honor/Huawei because of other people with similar devices having this issue.

@badf007 can confirm that for STF L09 aka Honor9.

Please re-open this as might not be related to #88
This issue is I think experienced when using FCM with other plugins. We were able to replicate this when we used nfet.net printing package.
In the case of this bug. it was the Downloader package
