我如何获得 Provider.of 的 memberId

Question

Heloo everybody. I want to ask you, how i can delete my ListView item,and send this to the Provider.of<Members>(context)

Answer 1

your delete item logic is wrong, just try this

void removeMember(String memberId) {
    _items.remove(_items.firstWhere((element) => element.idl == memberId));
    notifyListeners();
  }
