List Latest Post From Certain Categories On A Page

Hi,

I need to list the latest post from my category list (excluding two categories) on a Page. How can do this? I’ve search for plugins but they all seem out of date (I’m using 2.8).

I use flutter to handle images for each post as I use it as a CMS, and would ideally like to show the image of each last post on the list, but this is not essential at this time.

Any help would be appreciated!

Thanks, Richard
