No response

Hi @bennajah, thanks for the report. I’ve isolated the issue and found that the deprecation warnings are coming from firebase_auth. As mentioned in this comment, we don’t have a set timeline for the complete removal of these APIs at this point.

Hi @bennajah, thanks for the report. I’ve isolated the issue and found that the deprecation warnings are coming from firebase_auth. As mentioned in this comment, we don’t have a set timeline for the complete removal of these APIs at this point.

But the warning mentioned firestore plugin not firebase_auth

[SelaseKay]

Correct, the unchecked/unsafe warning is indeed related to cloud_firestore. However, in my previous comment, I was referring to the deprecation warnings, which appear to be originating from firebase_auth.
