Flutter: Implement Material Search bar to search data from a server async

Question

I am trying to implement material search in my flutter app using the SearchDelegate class.

I have implemented this with a local list of items. How can I use this to get list of items from a REST API asynchronously. I already have an API which gives the list of items for a given string. I just need to know how to do it asynchronously using the SearchDelegate class in Flutter.
