maui中实现加载更多 RefreshView跟ListView 跳转到详情页 传参（3）

效果如图

这里的很多数据是通过传参过来的的。

代码

例表页加入跳转功能：

  <ListView ItemsSource="{Binding Items}" ItemAppearing="OnItemAppearing" ItemTapped="OnItemTapped"   RowHeight="70" Margin="20">
后台加入 
 async void OnItemTapped(object sender, ItemTappedEventArgs e)
 {
   
     if (e.Item is Product tappedProduct)
     {
   
  Console.WriteLine($"Added item: Id={
     tappedProduct.Id}, ImageSource={
     tappedProduct.ImageSource}, ProductName={
     tappedProduct.ProductName}, Price={
     tappedProduct.Price}, Details={
     tappedProduct.Details} ImageSource={
     tappedProduct.ImageSource}");
         await Shell.Current.GoToAsync($"DetailsPage?id={
     tappedProduct.Id}&id={
     tappedProduct.ImageSource}&name={
     tappedProduct.ProductName}&price={
     tappedProduct.Price}&details={
     tappedProduct.Details}&img={
     tappedProduct.ImageSource}");

     }
 }

详情页：
