Ignoring header X-Firebase-Locale because its value was null.

[Quema100]

I am implementing an email/password login and sign-up system, which I designed to cancel account creation if the user does not verify their email within 5 minutes. During development, I encountered the following problem:

Ignoring header X-Firebase-Locale because its value was null.

To solve this problem, I've searched on Stack Overflow and Google, but I could not find a solution.

I have tried adding android:usesCleartextTraffic="true" to android/app/src/main/AndroidManifest.xml. I also attempted to sign up using a valid email and a password of at least 6 characters. I have tried reconnecting to the internet and re-configuring my Firebase login and permission settings, but I still have the Ignoring header X-Firebase-Locale because its value was null. issue.

How can I resolve this? Could this be an issue that can be solved by downgrading the emulator?

Here are my current versions:
Flutter: 3.32.4
Dart: 3.8.1
Android SDK: 35.0.1
JDK: 24.0.1
firebase_auth: ^6.0.0

Can I ignore this?
