Introduction to Flow Repeater Component
The Flow Repeater component in Salesforce is a feature used within the Salesforce Lightning Flow Builder. It allows for the creation of dynamic lists that can display a collection of records or data. This component is particularly useful for scenarios where you need to show multiple items in a flow, such as a list of related records, and allows users to interact with these items. I have already published couple of videos in my youtube channel covering this powerful component. You can find them below -
Data Source for Flow Repeater Component
When you will add the Repeater Component in the Screen element, you will find one option Under Configure Data Source section, named as Collection for Prepopulated items. This is the place where you will provide the collection of records. Any child element you will add inside Repeater will get the data from this collection. This feature is very powerful, because if you have 4 elements inside the collection variable, repeater component will be displayed 4 times with each 4 four records displayed in one of the repeated items.

You will also configure whether you will allow yours users to add new items or allow users to remove pre-populated items under Configure Display Options section. And definitely you can control when you want to display this component under Set Component Visibility section.
