How to filter api calls in flutterflow with dropdown

filtering api calls in flutterflow with dropdown menus: a comprehensive tutorial

this tutorial will guide you through the process of filtering api calls in flutterflow using dropdown menus. we'll cover the concepts, step-by-step implementation, code examples, and best practices to help you create dynamic and responsive user interfaces.

**i. understanding the concept**

the core idea is to let users refine the data displayed from an api by selecting options from a dropdown. when a user selects an option, it triggers an update to the api call, passing the selected value as a parameter. the api then responds with filtered data, which is displayed in your flutterflow app.

**ii. prerequisites**

* **flutterflow account:** you need a flutterflow account to build your application.
* **basic flutterflow knowledge:** familiarity with the flutterflow interface, widgets, actions, and data types is essential.
* **api endpoint:** you need a working api endpoint that accepts filtering parameters. this api should ideally return data in json format.

**iii. step-by-step implementation**

**step 1: setting up the api call**

1. **navigate to api calls:** in flutterflow, go to the "backend" tab and select "api calls."
2. **create a new api call:** click "add api call."
3. **configure the api call:**
* **api call name:** `getproducts` (or a descriptive name)
* **api call type:** get (assuming you're fetching data)
* **query parameters:** click "add parameter."
* **name:** `category`
* **data type:** string
* **is required:** no (it's optional for unfiltered results)
* **default value:** leave blank (for unfiltered initial load)
* **response:* ...
