Intercept Logout Adapter

The global onError handler will call logout if certain conditions are met:

mixin BaseAdapter<T extends DataModel<T>> on RemoteAdapter<T> {
  FutureOr<Null?> onError<Null>(DataException e) async {
    // Automatically logout user if a 401/403 is returned from any API response.
    if (e.statusCode == 401 || e.statusCode == 403) {
      await read(sessionProvider).logOut();
      return null;

    throw e;
