- 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.

one of the best videos of FF university
Looks like there is a miscalculation at 13m 45s, the values are supposed to be multiplied and NOT added
I just started the premium trial, and i am here to stay, this is out of this world! Native apps for mobile, windows, web pages and more? WHAT?
hey brother, whats your experience so far? have you learnt how to navigate through the templates?
Great explanation love all your videos
Thank you Team, It will be good to have option to filter unique records from list through FF UI. Without using any custom function
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?
The part I’m struggling with is having access to the actual Audio file to send it via API request. I can only get access to Audio Path after the recording is done
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.
Nope, individual to each user
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.
This was the hardest to follow so far. Anyone knows a channel with tutorials of small projects?
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 ?
The previous example stopped working after the June 12, 2024 update. If the list is empty, it no longer updates as expected
Null = blank; double = float number (for example 1,4 instead of integer)
This is exactly what I needed to see today. Thankyou 😊
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
Your expression is incorrect. It's type of espresso times number of shots, not type of espresso plus number of shots.
@11:10 Rebuild current page = refresh current item
Thank you, how ever I think you have to remake the video because you start saying its about applying filters and none of the examples (as far as I understood) show a filter application, instead, they were included many complex concepts such as API calls, or code, etc.
I hope you can make a video simplifying the concept of stage management
love this practical tutorial with example real world.
You should use an AI narrator.
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
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 ;)
Guys, can anyone help me, i have an issue, i'm creating marketplace of selling tickets of events, i've created an admin dashboard and i'm trying to add image and title... to listview card to home page from admin dashboard but i can't, can someone help me?
hello any support here? I think about quitting FF for another nocode app. Too bad FF dont listen to their users....
Thank you so much, I've been struggling with the new app state for my ecommerce site the past day
I feel that state management is a little complex task but it is very powerful.
I had never noticed the code expression capabilities of FF. great stuff
Thank you so much for this incredibly insightful video on state management in FlutterFlow! The step-by-step approach, clear explanations, and practical examples made the complex topic of state management much more accessible.This tutorial is not only helpful for those new to FlutterFlow(like me😁) but also serves as a valuable resource for experienced developers looking to hone their skills. Your commitment to educating the community is truly commendable. Keep up the great work, and I look forward to more content like this in the future! 👏👏👏
hey SIr, please help me, can you have the "add option labels" also for Choicechips? I know you have it on a dropdown menu, but that wuould be so helpful on a choicechips widget too. Please help me, I m developping an app right now and im blocked at this step. Thanks, Stuph
I mean to count each yes i could use a if choicechips =Yes, then value =1 , but now imagine i m doing a questionnaire.... It will be too long + dont know how to add those integers in this case
Can you make video for admin pnal for shop app
Thats Beautiful 😊
Is the only point of fire base to share it then?
this will only happen within your local devices, ultimately you will need firebase to store them and interact the data with other users
Thats amazing!
