- In this tutorial, we'll explore how to bind data in FlutterFlow. We will demonstrate all the different kinds of sources you can bind to and show you how to bind data from a single source or multiple sources to generate multiple child widgets.

Great video, thanks! One thing I learned from pushing FF apps to production is, the importance of setting up a proper query cache for each Backend Query API call (found in Query Cache Settings dropdown) and make sure that the Backend Query lives on containers or other widgets that don't rebuild (which will make the API call again for each rebuild). I hope this helps save you some time!
Advance and difficult things made easy 😊 Thank you FlutterFlow!
Thanks a lot for your explanations! You literally saved my app because now I know how to display my database data in a list!
Excellent as always! Still learning more! THX
Thank you very much! You could now create a 10 hour youtube course, that we can follow
I don't know if you'll see this or not, but if I've bound my widget to the backend query and then want to run calculations against the list data, for instance, a simple count of users for a dashboard, or total sales from a list of orders, where to I go to learn how to do that?
what about auto binding? where you update a field on the ui and it updates another field live on the page?
Great! Is there a quick way to make the app's widgets behave like a front end built in Vue/React? I mean, two-way data binding?
For example: when changing a widget, the others react dynamically. I believe we have to use actions to identify changes and make use of variables. Tks in advance!
Is there any way to change the currency depending on user location for e-commerce applications?
I have 2 data collections, posts and events... i wwant to merge the documents of both the details created by the same user in one component... there is no view that explains this... in one video it says use document reference... and one video it says document... unable to figure... also the fultter flow documentation has 1 liner explanation for what is document and what is document reference... pls help... stuck on this for 3 weeks...
I'm getting the posts of all the users in events cards rather I want very specific to event creator user...
Better way to do this maybe is to only bind to page state or app state and then have page/app state updated in actions flows etc. rather than having binding from multiple sources which will get unmanageable at some stage.
Nice feature, however, one question, how can we wrap the long text (if you notice what happened towards the end of the video, text is overflowing)?
Sure, you need to either wrap it in another widget like Container or if it's already wrapped in a row give it flexible or expanded
Broooo, thanks so much for this. T^T
I am not able to determine whether the method of explanation is difficult or is it difficult in nature
You got lost a lot and got distracted
yeah, this was a very strange video, it's like they don't know what they want to teach us.
there's no structure, just a bunch of info that makes sense to them, but not to us.
their other vids were good, but this one haa no structure or point, it just flips between a lot of different points without properly explaining them or giving any reason.
i'm disappointed as it was a subject i wanted to know a lot more about.
i hope they sort this out, as i'm starting to feel that they're getting way ahead of themselves and getting arrogant that we don't know what they know
@@neanda I'll be the 3rd to agree with this. The previous videos that were published felt manageable and although there have been gaps, I've been able to turn to communities like Reddit to fill those voids. It might be a lack of understanding on my part, but it feels like something is missing here. Maybe there weren't enough examples or the supporting components weren't broken down enough in an elementary way? I'm happy to pay (a lot of) money for very clear resources, but this took me further down additional rabbit holes.
@@neandayou can only understand if you have the overall view of how FF works
Seria interessante criar na construção das conexões por rest api a possibilidade de referenciar os documentos no que eu quero apontar dentro de uma bova coleção.
nice, just what i need
please make Pagination video on downScrolling at a time 10 pages
this is amazing info
Please add these to ads units banner and interstitial ads 😊
i cannot understand this weird edge case that you explain about a boolean, IsAndroid, would be used for a type String, then you just remove it. why would i need to know that? it's kind of put me off watching the rest of the vid. but i will continue watching it to see if it makes sense...
edit: nah sorry, i just had to turn it off. it wasn't what i was expecting re Data binding, something i was really looking forward to learning more about. this just seems too weird that you're giving examples of things that are not typical.
could you give us typical examples of data binding? thanks.
your other vids have been good so far though, but this, nah, it has no direction
their documentation is enough
