我想用 Getx 创建一个篮子,我将值定义为名称和价格,我想将基本产品添加到购物篮中。如何将字符串作为名称或双倍作为产品的价格添加到 PriceModel2 -RxList 中?

产品型号-

class PriceModel2 {
  String name;
  double price;

  PriceModel2(String name, double price) {
    this.name = name;
    this.price = price;
  }
}

添加功能

RxList<PriceModel2> basket = [].obs;

  urunEkle(String isim) {
    basket.add(isim);
    basket.add(isim<basket>[name]);
  }

界面

 ElevatedButton(
              onPressed: () {
                controller.urunEkle(
                    material["name"] );

感谢所有帮助。

试试这个:

型号:

x = 8
print('initial x', x, id(x))
while (x != 5):
    x = input("Please enter the number 5: ")
    print('final_x', x, id(x))

功能:

class PriceModel2 {
  final String name;
  final double price;

  PriceModel2( {required this.name,required this.price,});
}

界面:

List<PriceModel2> basket = <PriceModel2>[].obs;

void urunEkle(String isim, double fiyat) {
  basket.add(PriceModel2(name: isim, price: fiyat));
}

如果您使用空安全,此代码有效
