How do you integrate the Infinite Scroll Plugin with MvvmCross

Understanding MvvmCross Plugins

MvvmCross plugins are designed to provide abstractions of native functionalities. They are easy to use by installing NuGet packages in both your Core and platform projects[8]. However, if a plugin isn't explicitly referenced, it might not be loaded.

Using the Infinite Scroll Plugin

1. Install the Plugin: First, you need to install the Infinite Scroll Plugin via NuGet in both your Core and platform-specific projects. The plugin is available for Android, iOS, and UWP[9].

2. Bootstrap the Plugin: In versions of MvvmCross below 6.0, you need to create a bootstrap file for the plugin. This involves creating a class that inherits from `MvxPluginBootstrapAction` where `T` is the plugin loader type[8].

csharp
   using MvvmCross.Platform.Plugins;
   using Sequence.Plugins.InfiniteScroll;

   namespace YourApp.UWP.Bootstrap
   {
       public class InfiniteScrollPluginBootstrap : MvxPluginBootstrapAction
       {
           // Implementation
       }
   }
   

3. Loading the Plugin: If the plugin doesn't load automatically, you can manually load it in your `Setup.cs` file by overriding the `InitializeLastChance` method. This is particularly useful if the plugin doesn't load due to assembly name changes in newer MvvmCross versions[1].

csharp
   protected override void InitializeLastChance()
   {
       base.InitializeLastChance();
       // Manually load the plugin here if necessary
   }
   

4. Implementing Infinite Scroll: Once the plugin is loaded, you can implement infinite scrolling in your views. This typically involves binding a command to an event that triggers when the user scrolls to the end of a list. However, if you're using Xamarin.Forms, you can leverage the `CollectionView`'s `RemainingItemsThreshold` property to achieve this without needing an external plugin[2][5].

Troubleshooting

- Plugin Loading Issues: If the plugin doesn't load, ensure it's correctly referenced and that the bootstrap file is properly set up. For newer MvvmCross versions, check if the plugin needs updates to match the latest assembly naming conventions[1].

- Platform-Specific Issues: Ensure that the plugin is compatible with your target platforms (Android, iOS, UWP).

By following these steps, you should be able to integrate an Infinite Scroll Plugin with MvvmCross effectively.
