I tried to using flutter secure storage for some of my apps, what I realised when I uninstall the apps and install those apps again is that the data on flutter secure storage that I stored on previous apps that I uninstalled, still persist and got on those new apps. Does anyone know how to delete this data on iOS when I uninstall the apps?
It is working fine in Android - when I delete those apps on android and install them again, the data is fresh

Flutter Secure Storage uses KeyChain for IOS. and this is the default KeyChain behavior.

Potential solutions is to use Shared Preferences and create a flag to determine if the app was run before.

static const kSecureClearFlag = 'SOMETHING';
final hasRunBefore = pref.getBool(kSecureClearFlag) ?? false;
if(!hasRunBefore) {
secureStorage.deleteAll();
pref.setBool(kSecureClearFlag, true);
}

you can call this on your SecureStorageService initialization, and values won't be persisted across reinstalls.

Have the same issue with iOS app. And I've started to ask myself a question: is it possible that this data persist even between two apps which store same keys? This is unlikely I hope and the problem goes only to persistent of the storage after app was deleted.
