                          .read(orderDetailNotifierProvider.notifier)
                          .getOrderDetails(
                            outletIdentifier: outletDetails
                                    .firstOrNull?.identifier
                                    ?.toInt() ??
                                0,
                            type: selectedTable != null ? 1 : 2,
                            typeId: selectedTable?.tableId ??
                                selectedTakeAway?.takeAwayUid ??
                                takeAwayUuid,
                          );

I am not getting any error. <Please add a small sample to that can be executed to reproduce the problem. As a general rule, 100 lines is the maximum>

That's way too much code. Please make a minimal reproducible example.

Generally speaking, this error is expected and a mistake on your end. Chances are you used ref after an await without checking context.mounted
