This is used to clear the session tokens from local storage
Implementation
Future<void> clearCachedTokens() async {
final idTokenKey = '$keyPrefix.idToken';
final accessTokenKey = '$keyPrefix.accessToken';
final refreshTokenKey = '$keyPrefix.refreshToken';
final clockDriftKey = '$keyPrefix.clockDrift';
await Future.wait([
storage.removeItem(idTokenKey),
storage.removeItem(accessTokenKey),
storage.removeItem(refreshTokenKey),
storage.removeItem(clockDriftKey),
storage.removeItem(pool.lastUserKey),
]);
}
