How to Dynamically Filter API Calls in FlutterFlow

[@sgardoll]

You have single handedly, simply and elegantly explained something I have been battling with since starting with Flutterflow. The way you explain the background to how Flutterflow processes everything is incredible. THANK YOU.

[@gspassky]

I'm so addicted to this guy's way of explanation 🤤

[@bobbogenie]

You are the real mvp! This short tutorial gave me great chance to retrieve my data from my wordpress website based on this filtering method.

[@BGdev305]

Something this simple, there has got to be a way to do this in less steps / clicks / panels to visit!

[@rpeg18]

Wow, your explanations are so thorough! Thank you, and keep up the fantastic work👌

[@flutterflowexpert]

Great video FF!

[@raimundpock]

Great content! Helped me to solve the problem of query dependent null returns of json strings 😃👍 Thanks for this great explanation 🙏

[@mici159]

Thank you for the informative video! I've successfully implemented the data filtering based on categories and brands using your guidance, and it's working great. However, I'm currently facing a challenge with filtering a range of prices. Specifically, I'm trying to filter the list for items that are priced greater than or equal to $5 and less than or equal to $10. I've searched for solutions but haven't found any that fit my needs yet. Any suggestions or further guidance on how to tackle this would be greatly appreciated! Thanks again for your help!

[@shamsulazhar]

This guy is the best FF eplainerer. Moar of him please!

[@mjbjj]

This is extremely helpful, thank you! Can you do a video similar to this, but filter a list of documents from fire base that matches the date selected from a date picker and/or a calendar?

[@pete4910]

Great tutorial, please do one on "Map List Items" for a response from API

[@rabeezley]

Awesome video!

[@mohammedabdallah347]

Stunning! Thank you

[@gciola]

Incredible tutorial! Worked like a charm. There's still one more thing I could not solve: I have a listview header text that counts the number of results based in raw json response, not the filtered list. To get this new value, should I build a custom function or there's built in function for that? THANKS!

[@mods23-u1e]

I have tried this same but using a dropdown but its showing Red Mark its not applicable in that Any specific reason?????

[@inteligenciaadwords]

No specific reason, it's just that the system has updated a lot since this video, they don't update the video and we are totally lost, this video has nothing to do with it anymore, it's much easier to do that for sure, but anyway... .

[@cadufloripa]

What I don't get is how Flutterflow is supposed to know when to update list filtering when the state of checkboxes have changed. How are they linked in anyway? I'm trying to do the same with a TextField as filter and I can't get the list to update after user type something in it. :(

[@cadufloripa]

Found it! Just checking "Update Page On Change" property of TextField did the trick, if anyone come to that issue in the future.

[@joaovitorcordeiro7757]

This is really good and very helpful! How can I build a search from data loaded from API, which is crucial? Is that on the way or any specific way to achieve this with API data, please guide or share a tutorial around that.

[@SM-rd5wn]

did you find a solution?

[@XeiDaMoKaFE]

please teach us how to use the last item , without pagination , using the unix timestamp of the last entry of an api call in the url of the next api call and repeat until there's no more entries left

[@PorygoneLabs]

Excelent!, thank you so much!

[@edwinbolanos1039]

Thanks for your great product. I have one question. Could you please explain me how to filter appstate information. For example an appstate of products filter by category, with a dropdown that allows the user to filter the category.

[@HeavyT93]

How do we make this work if the filter info is coming from a drop-down widget? Im having trouble as the widget state is red when trying to see if that filter is in the product's attributes. And I cannot seem to make my drop-down list a a list-string. I think that is part of the issue but can't figure it out

[@RedCloudServices]

If your backend was graphql you would request only the attributes you need at query time rather than filter the response 😊

[@sunfarmfoods6361]

Hi, I am not getting the Filter List Items Option in the latest version of FF. Or Does this work in a particular JSON structure only?

[@godonholiday]

This is great, could you explain how you pulled the title and brand into the fields in the list view? Did you use map in the column child section?

[@FlutterFlow]

Sure, kzbin.info/www/bejne/npyliImtp5ysjrM

[@GustavoSantos-v7d]

I'm struggling to figure out as well.

[@EdvanSouzaLive]

Hi! Great tutorial. I came from Bubble and i have so many difficulties with FF about data structure and to call the data. Especially when exits relations. I'm trying to make a App that the user can have many Skills. I made a Collection with the skills pre-registered. In the User Collection i created a userSkills relataded as list of Skills. When the user are in the Register, i show a list of Skill in a Dropdown (with search cause are a lot skills to choose). I created a App State to get the skills to show them on a warp. This is for a user see what skills he choose and dele if are a mistake. But what should to be simple is a nightmare (because in Bubble everything is more fluid in that question). In the FF i need to make a query of a query, of a query... Its so frustating when put a button (that are inside of a wrap - that have the children of a list os AppState) and, at the end of process, that i only need the SkillNames... and they aren't there. For love of god... can you explain how this work? I know and i have see the power of FF Sorry for my rant... 😮‍💨😢😭

[@cxacademy5554]

The "product response" didn't come through for me. The API call was successful, but when it came to adding the action, the API doesn't appear. 4:31

[@abbasloda1]

Hey team , can somebody help me . Any list view I create when there’s only one element or empty crashes . Is there a better way to go about it ?

[@LoganMullinixdoes]

Is it possible to have users login to an app and then see information’s specific to them through an api call? Like only show them access to the things they have access to?

[@FlutterFlow]

Yep, using authentication through Firebase: kzbin.info/www/bejne/mHiWYaiAaphjY6M

[@pratimadudhewar3680]

How can we implement this same logic for API's. I mean whenever i chnage the dropodown value or radiobutton i want to call API with fresh widget values and set it to listview..

[@SM-rd5wn]

did you find a solution?

[@improvementbeyond2974]

Hello there is no filter list items option for me what I am doing wrong

[@johnwilliams1620]

Hey At @Flutterflow guys Im buidling an app using this tool and Im wondering if it is possible to allow the user of the app to edit the size of a container and maybe allow for font changes on some text? I know there is a custom function I can build using text editor but what about creating a resizable container?

[@danzreview]

this is awesome

[@mauromiotello]

Can you share this test project ?

[@jonas01210121]

Hi,Does anyone know how to apply this type of filter to a response from a field that is an array. loo I did as is but it doesn't work??????

[@marcdu7]

in the last version this not function, omg

[@amsneo]

You guys are awsome I really think FF should be much more popular

[@FlutterFlow]

We agree:)

[@HarshSharma-ln6xq]

This is not applicable to firestore query result... Is there a similar way to filter results from firestore query?

[@alguemlima]

Also interested on this

[@RR-et6zp]

wouldn't you just filter at the database level? when would using this API way make sense?

[@hostbybits-webhostingforre6845]

Most of the backendS uses API. if the data is not in your database you need to access it through an API

[@theBCBOMBER]

Hi Flutterflow team!! This was a really great tutorial, but I tried it and realized it doesn't work quite the same for the Swipeable Stack widget. I thought ListView and Swipeable Stack would be interchangeable for this method but I was wrong. Is there any way you can upload a tutorial on how to properly filter with the stack? Thanks so much!

[@johnfleming1229]

This is crazy complicated for such a simple solution! A filter icon, relate a field in an iterable == a value in another widget.. limited ops like equal to, in, logical cascades of && ||..

[@vikassable3468]

how to filter with search field

[@PKN7oficial]

atualizem!

[@GyroO7]

I don't appreciate all these custom functions in tutorials and templates Promoting this as a no code tool then bringing some dart code out of nowhere is pretty annoying It just hinders the smoothness of workflows
