I don't know much about dart, but I think the problem occurs because
final prevUser = FirebaseAuth.instance.currentUser!;
won't store currentUser object but instead the reference to it.
So when trying to access prevUser the latest FirebaseAuth.instance.currentUser! is provided.
@superflyer11
I think the way user.delete() works is, it deletes the current user and not necessarily the user represented by the User instance.
You can try something like below to see if actual user is getting deleted or not:
try {
await FirebaseAuth.instance.currentUser!.delete();
} on FirebaseAuthException catch (e) {
if (e.code == 'requires-recent-login') {
print('The user must reauthenticate before this operation can be executed.');
}
}
Is there a way to delete the user after logging into another account? I am trying to achieve something like this
try {
userCredential = await FirebaseAuth.instance.currentUser!.linkWithCredential(oAuthCredential);
return userCredential;
} on FirebaseAuthException {
try {
userCredential = await FirebaseAuth.instance.signInWithCredential(oAuthCredential);
// delete the previous user account in case linking the two accounts is unsuccessful
return userCredential;
} on FirebaseAuthException catch (e) {
errorCallback(e);
}
}
