Flutter Flow - Dynamic DropDown Tutorial

In this Flutter Flow tutorial, we'll learn how to create dynamic dropdown menus that respond to user input. Dropdowns are a common UI element in many mobile and web applications, and Flutter Flow makes it easy to create them without writing a single line of code. With dynamic dropdowns, we can build more interactive and user-friendly interfaces that adapt to users' needs and preferences. We'll cover the basics of dropdowns, how to bind them to data sources, and how to update their values based on user selections. By the end of this tutorial, you'll have a solid understanding of how to create dynamic dropdowns in Flutter Flow, and you'll be able to apply this knowledge to your own projects. Whether you're a beginner or an experienced Flutter developer, this tutorial has something for you. So, let's get started and learn how to build better dropdowns in Flutter Flow!

I loved the video, I was trying to do that... But I ended up not doing it your way because the list was too simple to have to require the backend (this can overload the server for silly things). So far I haven't seen anyone teach how to do it without a backend, but I managed to do it here. using a normal dropdown 1. Create state of type string and list (cars list) and didn't add anything to it, then I put the "Dynamic DropDown" to have the list according to the string (cars list), whatever is in the string is in the list!!! 2. Create the lists in new states of type string and list each with a different list (State Audi: car1, car2...) (State Ford: car1, car2...). 3. Add what you want to the list in the first dropdown normally (in this case audi and ford) 4. Add a Conditional Action if ("First Dropdown" == "audi") update the state string "cars list" to state string "Audi" And that should make the second list dynamic

[@RedCloudServices]

what do you recommend if there is a bigger tree structure for conditional dropdowns? can flutterflow provide an api for list values?

[@krypto1530]

@@RedCloudServices standard setup would apply, you should try asking chat GPT with more specifics on what you're trying to do

Thanks. How to cascading two dropdown using a local list to reduce query to database?

[@nkofr]

Nice. Do you know if it's possible to bind data so that we can retrieve an ID from the dropdown list, that would be useful, for example if the app is multilanguage

[@zeuski117]

Friend, thank you very much, I appreciate it so much, you just saved me many hours of work, I was doing the same as you but I did not add the conditions correctly.

[@Lambs-sx7hp]

and another issue when i click my drop down bo the name doesnt show it shows [campus_dd Documents -> output 0] not the name anyhelp

[@threesentertainment]

Thank You Brother

[@StivenOchoa]

How its works for a dropdown where the selected option its a document reference? for example, i have a collection called states and i need asigned to a product on products collection, where state field its a document reference

[@PropiedApp]

That was exactly what I needed!, thank you so much! I wonder if you also know the solution for this: Since I have several documents (some are the same car brand) the options for "FORD" in the drop down are repeated several times, do you know how I can make each brand appear only once? I was looking for some kind of filter or "do not repeat" function but I can't find anything like that

[@rafaelosiris]

how to do this but with ApiCalls. Because the api calls don't have widget and the workoround is very complicated.

[@andreasfun9591]
