I just dont quite understand why is this happening to me.I followed all the steps as in https://flutter.dev/docs/deployment/android to upload my first version.There was something wrong in it.So I created another (a previous kind of backup project)flutter project and modified it to the existing one.I changed the com.flutterappstareawayvrsn1 which was initially something else.
I have put the key and it still shows the error:
Your Android App Bundle is signed with the wrong key. Ensure that your App Bundle is signed with the correct signing key and try again: :********************
How do you fix this thing?
