参数类型“Widget Function（BuildContext，Object？）”无法分配给参数类型“Widget Function（BuildContext，dynamic，VxStatus？”
尝试使用 Vxbuilder 或 Vxconsumer 更新购物车总数，但会弹出此错误
class _CartTotal extends StatelessWidget {
final CartModel _cart = (VxState.store as MyStore).cart;
@override
Widget build(BuildContext context) {
return SizedBox(
height: 200,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: [
VxBuilder(
mutations: {RemoveMutation},
//notifications: {},
builder: (context, _ ){
return "\$${_cart.totalPrice}"
.text
.xl5
.color(context.theme.accentColor)
.make();
},
);
30.widthBox,
TextButton(
onPressed: () {
ScaffoldMessenger.of(context).showSnackBar(SnackBar(
content: "Buying not supported yet".text.center.make(),
));
},
style: ButtonStyle(
backgroundColor:
MaterialStateProperty.all(context.theme.buttonColor)),
child: "Buy".text.xl3.color(Colors.black).make())
.w32(context),
],
),
);
}
}
