Introducing Custom Data Types in #FlutterFlow

In this short video I introduce you to Custom Data Types. You can now define a custom data type within #FlutterFlow which can then used throughout your #nocode #lowcode application. For example I created a custom data type called User which contains a full name, age and a list of favourite fruits. I used an App State variable which is using the Custom Data Type to persist all the values within my application. I then used the UI to manipulate the values stored within the App State. I also show how these can be passed around a very simple Custom Function.

There are so many use cases for Custom Data Types and I hope this video provides some insight to how these can be used in your own projects. Enjoy!

Hi Steve, Thanks for the video. By the way, I'm wondering how can we can add option from drop down menu to list like you did in the video without using app state?

Hey ! Thanks for the great video... I saw that new icon this morning and thought it would be a game changer. From what I understand, this is like a local database right ? But right now, I am puzzled. I wanted to store my API response (a 3mo JSON file) through Data Types, creating a data type field for each field in my response, and inject the data through an action (update app state). It doesn't work. So my question is : is it really doing what I am trying to do ? :D

Hi! Great video!
Do you know what are the size limits to use data type in App State?

[DavidHust]

I'm guessing this isn't needed as much for when you get data from Firebase since it already has data types? This would be more for APIs that return JSON since those aren't type safe?

[jimvh]

So it’s in fact just data tables but stored inside the app if persistent if I’m correct. Would these just act as single row data profiles containing a user’s preferences? What use cases would there be?

Thank you.
I am wondering How would custom data types apply to web apps?

[MateuszKolodziejczyk]

Hey Steve! Can I use this app state to mimic local storage databases?

[victorcharp]

what's the plus value compared to firebase ? no query ? but is there something we can't do with firebase which is possible with custom data types ?
