Flutter Foreground Notification (Android Emulator)

[mado-bohsali]

For Android emulators, once I receive a foreground notification a stack trace appears in my console:

D/FLTFireMsgReceiver( 7010): broadcast received for message

You've likely not specified the icon that should be used correctly, please cross-reference what you've done with what's in the docs and the example app

[mado-bohsali]

I still receive the message:
broadcast received for message

[MaikuB]

There's not much else I can tell you as there aren't any known issues with around showing this so you'll need to either take a closer look or have someone check the work you've done

[mado-bohsali]

May you have a look?

[mado-bohsali]

What firebase pub.dev versions are you using?

[MaikuB]

May you have a look?

As this is something I do in my spare time and there are fewer contributors, If you need someone to take a look then you'd need to reach out to wider community.

What firebase pub.dev versions are you using?

The version of firebase isn't relevant to the error (note: i'm not using it either), if you stripped the away the code to just show a notification using only this plugin then you should run into the same issue. As mentioned before, the issue you see happens when the icon hasn't been configured correctly so you'll need to take a closer look at how you've done so. This requires knowledge on how Android manages resources to ensure you put it the image in the right location and specify it correctly. If you are using FCM, note that they have an example app that uses the plugin together with this one as well. You can clone the repo and look at the example app associated with this plugin and run it as well

Thanks Michael for your input! The whole process worked. Genuine wishes, Mohamad El Bohsaly
