flutter - Flutter Slidable SlidableAction 调用 onPressed 即使它没有被按下

Question

我正在使用一个名为flutter_slidable的库。下面是我的 fetchItems 方法

static Future<List<Item>> fetchItems(String url) async {
    try {
      // pub spec yaml http:
      // import 'package:http/http.dart' as http;
      final response = await http.get(
          Uri.parse(
              url),
          headers: {
            "Content-Type": "application/json",
            "Authorization": "Bearer tltsp6dmnbif01jy9xfo9ssn4620u89xhuwcm5t3",
          }) /*.timeout(const Duration(seconds: Config.responseTimeOutInSeconds))*/;

      final List<Item> itemsList;

      if (response.statusCode == 200) {
        itemsList = json
            .decode(response.body)
        // In event of failure return line below
        //.cast<Map<String, dynamic>>()
            .map<Item>((json) => Item.fromJson(json))
            .toList();
      } else if (response.statusCode == 401) {
        itemsList = [];
      } else {
        itemsList = [];
      }
      return itemsList;
    } catch (e) {
      if (kDebugMode) {
        Logger().wtf(
            "FetchItemsException $e \n\nResponseStatusCode ${statusCode!}");
      }

      rethrow;
    }
  }

下面是我填充的页面的代码

class ClassListWithSearchOnAppBarCustomCard extends StatefulWidget {
  const ClassListWithSearchOnAppBarCustomCard({Key? key}) : super(key: key);

  @override
  _ClassListWithSearchOnAppBarCustomCardState createState() =>
      _ClassListWithSearchOnAppBarCustomCardState();
}

class _ClassListWithSearchOnAppBarCustomCardState
    extends State<ClassListWithSearchOnAppBarCustomCard> {
  List<Item>? itemsList;

  Future populateItemsList() async {
    final itemsList = await AsyncFutures.fetchItems(
        "https://api.json-generator.com/templates/ueOoUwh5r44G/data");

    setState(() {
      this.itemsList = itemsList;
    });
  }

  @override
  void initState() {
    super.initState();

    populateItemsList();
  }

  onSearch(String searchValue) {}

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          elevation: 0,

                          populateItemsList();
                        });
                      },
                      child: ListView.builder(

                                itemsList![index].title ?? "",
                                itemsList![index].subTitle ?? '',
                                itemsList![index].imageUrl ??
                                    Config.nullNetworkImage),
                          );
                        },
                      ));
                }
              },
            ),
          )
        ]));
  }

  deleteSlidableAction(BuildContext context, String? itemId) {
    
    setState(() {
      itemsList!.removeWhere((item) => item.id == itemId);
    });
  }

  dialogSlidableAction(BuildContext context, String? itemId) {
    print(itemId);
  }

  void onDismissedRemoveItem(String itemId) {
    setState(() {
      itemsList!.removeWhere((item) => item.id == itemId);
    });
  }
}

我遇到的问题是，删除和对话框的 onPressed 的 SlidableAction 甚至在它们被按下之前就被调用了，并且填充的列表项都被删除了
