State Management | FlutterFlow University

In this video, we delve deep into state management in FlutterFlow. We start with understanding why state management is essential, from tracking user login status to managing filters for lists. The tutorial elucidates how widgets and variables play a vital role in FlutterFlow's state management. Viewers will gain insights into how certain widgets inherently manage their state, and how to utilize widget state for dynamic data binding. The tutorial progresses to expound on the three types of variables in FlutterFlow: component state variables, page state variables, and app state variables. Each has its own scope and utility, ensuring cleaner and more efficient app development. The video showcases how to define, modify, and integrate these variables seamlessly, emphasizing potential pitfalls like null values and their implications. The tutorial wraps up with a practical example of a coffee checkout page, illustrating the real-world application of state management principles in FlutterFlow. Whether you're a beginner or a seasoned FlutterFlow developer, this video serves as a comprehensive guide to mastering state management.

Looks like there is a miscalculation at 13m 45s, the values are supposed to be multiplied and NOT added

This is exactly what I needed to see today. Thankyou 😊

Thank you Team, It will be good to have option to filter unique records from list through FF UI. Without using any custom function

[chidude]

I had never noticed the code expression capabilities of FF. great stuff

[valirmasha]

love this practical tutorial with example real world.

Cleared up soooo much confusion on my end. So every state management is local? That's what I was confused about. I previously thought you could update a widget and impact someone else's device.

it appears there is now no option of allowing null in a text box. when I assign a page parameter that allows null, the text box forces me to provide a default with no other option. The interface has changed since the training what am I missing I have to allow null. It appears the first time you don't have an option you have to enter in a default value, but when you edit it you can delete the default and save.

Thank you FF team for all these amazing tutorials 🎉❤ Could you please show us how to send a recorded audio to a backend (other that Firebase) via API calls?

Excellent Tutorial! Enthusiasm and pride of the product are just radiating from your voice and intonation. Perfect level of information and flawless editing. You should train an AI model to have your voice, knowledge and passion and sell it to other software companies so they can publish engaging tutorials like yours ;)

Thank you so much, I've been struggling with the new app state for my ecommerce site the past day

[stivenramirez]

The previous example stopped working after the June 12, 2024 update. If the list is empty, it no longer updates as expected

so exactly what happened here ? when you give the text widget a default variable value, what happened in the backened that allows it to have nullable value ? you typed name, and suddenly now it can be nullable ? that doesnt make sense to me, can you please explain that ?

Null = blank; double = float number (for example 1, 4 instead of integer)

i srill dont understand appstate, i watched so many videos and read docs but. i just dont get it. i dont get how to use it, i dont get why to use it

[koen.mortier_fitchen]

This was the hardest to follow so far. Anyone knows a channel with tutorials of small projects?

[developerzull]

I feel that state management is a little complex task but it is very powerful.

Hello, I'm using Supabase and an AppState for my shopping cart. I've created two users to test de App, but when I add a producto to cart it appears in both account users. It is normal? Because I'm in test mode
