I am trying to log in using Facebook to the app created with Flutter,
if I use the debug version of the app, the login works, but if I download the release version I get this error "Facebook key hash does not match any stored key hashes" with a hash key, I put the key on the https://developers.facebook.com/apps/APP_ID/settings/basic/ but still not working.
Can you help me?
Thank you all!
I also ran into tha issue that when I upload my APK to Play Store and install app
from it, it shows some Login failed error meanwhile it does work in debug mode.
What you have to do:
Go to Play console - link
Select Release Management → App Signing
You can see SHA1 key in hex format App signing certificate.
Copy the SHA1 in hex format and convert it in to base64 format, you can use this link do that without the SHA1: part of the hex.
Go to Facebook developer console and add the key (after convert to base 64) in the settings → basic → key hashes
Solved this thanks to mouzmisadiq and gustavo-lopes
