I am building an admin panel in flutter. i want to implement an feature that super admin can delete or disable an existing users account.

anybody know how to do this, iam using flutter 2.8 i have no idea how to do it.

CodePudding user response：

In the Flutter SDK (and other client-side SDKs) there is only the option to delete the currently signed-in user. There is no way to delete another user by their UID, as that would introduce a significant security risk.

The option to delete a user by their UID does exist in the Admin SDKs, which are SDKs that are designed to run in trusted environments, such as your development machine, a server that you control, or Cloud Functions/Cloud Run. This type of SDK cannot be used in your Flutter (or other client-side) app.

If you're trying to build application admin logic into a Flutter application, you'll usually split that in two parts:

1. Build a custom back-end API (on your own server or through Cloud Functions/Cloud Run) where you have an endpoint for each feature you need. In there, you'll need to ensure that the user that calls your custom API is authorized to do so, for example by checking their UID against a known list, or checking for a custom claim.
2. Then you build the Flutter UI on top of this custom UI, passing your ID token to the custom API so that it can check whether the caller is authorized to delete the user (as otherwise you'll be creating the same security risk I mentioned earlier).

I recommend also checking this answer that I just gave on a different, but related, question: Password Authentication with Vaadin Flow and Firebase

First add firebase_admin package to your project.

Then you need to add your firebase project into it.

var app = FirebaseAdmin.instance.initializeApp(AppOptions(
credential: ServiceAccountCredential('service-account.json'),

Then you can use this following code:

Future<void> deleteUser(String uid) async {
   await app.auth().deleteAccount(uid);
}
