This similar issue https://github.com/firebase/firebase-android-sdk/issues/1662 was raised 6 months ago and has many people waiting for a solution. However, there is still no one assigned nor is the single contributor responding to questions on progress. I am therefore raising a new issue in the hope that it will receive some attention.
Many thanks.
Run debug (in VSCode in my case) on the emulator or a USB connected device and the messages will soon appear, and continue to do so.
Not applicable - see environment details above for gradle dependencies.
I found a few problems with this issue:
Have the same issue:

firebase_core: ^0.5.3
firebase_auth: ^0.18.4+1
firebase_analytics: ^6.3.0
firebase_database: ^4.4.0
firebase_storage: ^5.2.0
Same issue here.
Same here as well
Same here with:
firebase_core: ^0.5.3
firebase_messaging: 8.0.0-dev.10
I am facing this issue as well and it really bothers as I'm not sure if it's the code issues or what. For me, I've tested a couple of times regarding the dependencies and turns out removing the firebase analytics works for me. Hope it helps
Same issue:
firebase_core: ^0.5.3
firebase_auth: ^0.18.4
cloud_firestore: ^0.14.4
same here:
# firebase
firebase_core: ^0.5.3
firebase_auth: ^0.18.4+1

@NarHakobyan Seems like https://github.com/firebase/firebase-android-sdk/issues/1662 has started up again so hopefully we'll get resolution there. @ashwinraghav is responding on that issue and @vkryachko is assigned.
@GrahamDi thanks for info 🙋♂️
