As a passionate developer, I've always been eager to find new ways to optimize my workflow and improve my app development process. One of the tools that have greatly impacted my work is FlutterFlow, a powerful visual app builder that simplifies complex tasks. With its custom actions feature, I've been able to efficiently fetch lists and documents, which has significantly enhanced my productivity.

In my journey of exploring custom actions in FlutterFlow, I discovered some top techniques for fetching lists and documents that I'd like to share with you:

Streamline your database structure: Before diving into custom actions, it's essential to have a well-organized database structure. This makes it easier to retrieve the required data using custom actions and reduces the complexity of your queries.

Leverage Cloud Functions: By integrating Cloud Functions with FlutterFlow, I can write server-side logic that runs in response to specific triggers. This helps me create powerful custom actions for fetching lists and documents with ease.

Utilize query filters: I've found it incredibly useful to incorporate query filters when fetching lists or documents. This enables me to narrow down my search and retrieve only the relevant data, making the process more efficient.

Optimize pagination: To avoid overwhelming the app with large amounts of data, I implement pagination when fetching lists. This technique breaks the data into smaller chunks, enhancing the app's performance and user experience.

Master error handling: When working with custom actions, it's crucial to anticipate potential errors and handle them effectively. This ensures that the app runs smoothly, even when unexpected issues arise during data retrieval.

By incorporating these top techniques into my workflow, I've been able to master custom actions in FlutterFlow, leading to more efficient and powerful data retrieval. This has not only saved me time and effort but has also contributed to the creation of more robust and dynamic apps. If you're looking to elevate your app development skills, I highly recommend diving into FlutterFlow's custom actions and exploring the potential it holds for fetching lists and documents.

I'm testing the code on a collection that has a DateTime field, and even looking for a String field, when running the code the following error is returned: "Uncaught (in promise) Error: Expected a value of type 'DateTime?', but got one of type 'String'".
Could you tell me how to solve it? Thanks and well done for the video!
Note: I tested with a collection that does not have Datetime fields and it worked fine.

Hmm when I try to run this I get an error for permissions... even though I can do a query normally

I face a problem if we are bringing data using actions which are Async in nature then the children down the tree need to access the info which might not be available in time. How to deal with the situation ?

Hi Dimitar, I want to assign the List of CarsRecord into a AppState variable. In AppState, I see only DocumentReference in the type, I cannot see the CarsRecord even if I have collection declared in the FlutterFlow. How do I create List of CarsRecord in the AppState?

Is this code still available in github? I cannot seem to find it.

Wtf? Didn’t explain….anything at all. Just repeating exactly what we can already see on the screen. 😂
