Денис Акулов's questions

你需要为此发送一个post请求你需要收集Map中所有TextFiel的值你需要做什么TextEditingController是body测试数据，据我了解，更改字段时，你需要向地图添加一个值。如何做得更好请告诉我。

告诉我如何填写我在单独的小部件中拥有的项目，或者我需要在那里

Group84ItemWidget()

class OrderTestWidget extends StatefulWidget {

  OrderTestWidget({Key key, this.title}) : super(key: key);

  final String title;
  @override

}


class _OrderTestWidgetState extends State<OrderTestWidget> {


  var breedList = Order();
  void getCatData() async {
    var catJson = await CatAPI().getCatBreeds();
    print(catJson);
    var catMap = json.decode(catJson);
        print(catMap);
    setState(() {
      breedList = Order.fromJson(catMap);

      print(breedList.orderdata);  
    });
  }

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

  @override

            )
          ],
        ),
      ),

}

模型

@JsonSerializable()
class Order {
  String apistatus;
  String apimessage;
  List<OrderData> orderdata;
  Order({this.apistatus,this.apimessage,this.orderdata});

  factory Order.fromJson(Map<String, dynamic> parsedJson) {
  var list = parsedJson['data'] as List;
   // print(list.toString());
    List<OrderData> dataList = list.map((i) => OrderData.fromJson(i)).toList();        
    return Order( 
           apistatus:parsedJson['api_status'].toString(),
           apimessage:parsedJson['api_message'],    
           orderdata: dataList
           );         
      }
}

这里的 Group84ItemWidget 只是静态填充的左侧数据，我需要从请求中用数据填充它们，而 Group84ItemWidget 也指 Group81ItemWidget 有一个 gridview with users

class Group84ItemWidget extends StatelessWidget { 
  void onButtonPressed(BuildContext context) {

        borderRadius: BorderRadius.all(Radius.circular(35)),
      ),

                itemCount: 15,
                itemBuilder: (context, index) {

                 return Card (
                 child: Group84ItemWidget(),
                 );
               },
              ),
            ),
          ],
        ),
      ),
    );
  }
}

我可以动态创建组，每个组都有自己的价格。

该网站有一个表格：

有必要在 1-10 范围内的第一组一个价格从 10-20 另一个等。最后一组根据请求显示文本价格在最后一组字段中输入的任何文本：

group_count =1     
diapazon_ot[group_count] =  1;
diapazon_do[group_count] =  10;
czena_na_cheloveka[group_count] =  5;

group_count =2      
diapazon_ot[group_count] =  10;
diapazon_do[group_count] =  20;
czena_na_cheloveka[group_count] =  10;

group_count =3      
diapazon_ot[group_count] =  20;
diapazon_do[group_count] =  30;
czena_na_cheloveka[group_count] =  15;

group_count =4     
diapazon_ot[group_count] =  30;
diapazon_do[group_count] =  40;
czena_na_cheloveka[group_count] =  "Цена индивидуальна ";

最后一组没有问题，像这样可以是成年人这是来自天主教徒的形式

//выше этого индивидуально
if (adults > diapazon_do.length) {
    alert( 'Максимум' );                                          
    var  person_max = czena_na_cheloveka[diapazon_do.length];
}

在这里，据我了解，需要循环整理，但我就是不明白怎么做。
