Update SHA-1 Key in Firebase project setting
Also check your google cloud project api key setting and also add SHA-1 Key credentials if you have Key restrictions.
I have an app in the playstore created with kodular (similar to appinventor),
I started over with flutter and I like the result
However, when I try to deploy on the playstore, the app is refused with a reason: Your Android App Bundle is signed with the wrong key.
Do I have the upload_cert.der file, and how can I sign the flutter app with that certificate?
(i use android studio)
Your Apps key should match otherwise you will not able to update the apps. You can find the keystore in kodular

Is the issue from phones or from the app I wored if I publish it on Google play
It's doesn't work pls help me.
The error appears because Android Studio signs your apk with the debug.key by default. Documentation is here. When you sign it with the release key as Google Play requires, the problem will go away.
Installing an app on your phone requires that the APK file is signed with a certificate. When you install an app to your phone with Android Studio, it generates a keystore with a certificate and signs your app. This generated keystore is insecure and can only be used for development. Most likely your other phone is not allowing you to install the app signed with this insecure key.
To fix this, you need to generate a certificate to sign your APK with. For instructions how to do this, read the official documentation
