Overview of Changes:

Lazy Loading Implementation:

The changes primarily introduce lazy loading to optimize the performance of the campus app. This involves adjusting how data is fetched and presented, ensuring that content is loaded progressively as the user scrolls, rather than loading all content at once.
I modified all widgets that could use ListView.builder to support lazy loading, improving memory usage and responsiveness.

Error Handling and UI Feedback:

The changes also include updates to the user interface to show loading indicators or error messages when lazy loading encounters issues.

More CachedNetworkImage Implementation:

I found some files along the way that were independent from ImageLoader, so I made them use CachedNetworkImage instead of image.network
