Querying Related List Fields Within One Or More Documents - FlutterFlow

Описание: In this short tutorial, I will demonstrate how to pull data from multiple list fields with one or several documents, as that data relates to each other, and display it in listView query. Sometimes it's useful to be able to pull list data from a document and have it associated, for example, if you have a user cart document and want to show the name of an item, the price of that item and the total quantity the user is wanting to purchase, you need to be able to pull the data from each of the list fields and show the information next to each other in a query.
