// 维修记录项组件@Componentstruct RepairItem {  @Prop item: RepairRecord; // 使用Prop装饰器接收参数    build() {    Column() {      Text(this.item.carModel)        .fontSize(16)        .fontWeight(FontWeight.Bold)      Row() {        Text(`里程: ${this.item.mileage}km`)          .fontSize(14)        Text(`费用: ¥${this.item.cost}`)          .fontSize(14)          .margin({left: 10})      }      Text(this.item.repairDate)        .fontSize(12)        .fontColor(Color.Gray)    }    .padding(10)    .borderRadius(8)    .backgroundColor('#f5f5f5')    .margin({bottom: 8})  }}
// 维修记录接口定义interface RepairRecord {  id: string;  carModel: string;  mileage: number;  cost: number;  repairDate: string;  nextMaintenance?: string;}
