🐛 [firebase_core] Accessing hidden method Lsun/misc/Unsafe

[casvanluijtelaar]

Bug report

Describe the bug
after updating all firebase dependencies to the new ones (firebase_core usage etc...), terminal started being spammed with
Accessing hidden method Lsun/misc/Unsafe;->putInt(Ljava/lang/Object;JI)V (greylist, linking, allowed)
and similar.

Steps to reproduce

Steps to reproduce the behavior:

took an existing project and migrated it to the new firebase plugins:

  firebase_auth: ^0.18.4+1
  firebase_core: ^0.5.3
  firebase_storage: ^5.2.0
  cloud_firestore: ^0.14.4

Expected behavior

app behaves like normal. constant warning are being thrown in the console, downing out any useful debug messages.

---

Additional context

this is not a breaking bug, it seems like one of these plugins is using outdated / unsafe operations? Haven't run into any point where this breaks the functionality of the app, but it's something to look into

Don't have a repro case for this but I've seen it in a lot of logs in other issues.

[casvanluijtelaar]

might be unrelated, but

seems to show up from time to time too, since migrating.

[casvanluijtelaar]

seems to be very much related, if not the same as #4090 and firebase/firebase-android-sdk#1662? can be closed?

[markusaksli-nc]

It could be related but these messages are different enough to be considered separate issues I think. One of the members can close this if it turns out to be caused by the same upstream issue.

[flakerimi]

Its related with this too flutter/flutter#27095

[zaenury]

@casvanluijtelaar You can fix this by turning off the backup.
Add this tag on your file "android > app > src > debug > AndroidManifest.xml":

<application android:allowBackup="false">

Run

flutter clean
flutter run
flutter create .

Here is some information about your problem https://developer.android.com/guide/topics/data/autobackup .

[russellwheatley]

Closing as there is nothing to be done from a Flutterfire perspective. Internal android warnings that have been resolved on android 11, but will never be resolved for android 10. See here
