How can I implement virtual scrolling in Angular Material?

To implement virtual scrolling in Angular Material, you can use the cdk-virtual-scroll-viewport component. This allows you to efficiently render large lists by only displaying the items in view.

What are the prerequisites for using virtual scrolling?

You need to have Angular Material and Angular CDK installed in your project. Make sure to import the necessary modules in your app module.

Can you show me a code example?

Sure! Here's a simple example:

<cdk-virtual-scroll-viewport itemSize="50" class="example-viewport">
  <div *cdkVirtualFor="let item of items" class="example-item">{{item}}</div>
</cdk-virtual-scroll-viewport>

This will create a virtual scroll list where each item has a height of 50 pixels.

What if I want to customize the item size?

You can customize the item size by changing the itemSize property in the cdk-virtual-scroll-viewport. Just set it to the height of your items.
