filtering api calls in flutterflow with choicechips: a comprehensive guide

this tutorial will walk you through implementing api call filtering in flutterflow using choicechips. we'll cover everything from setting up your api connection to creating the ui and writing the custom code needed to dynamically filter your data.

*understanding the goal*

the aim is to allow users to select one or more options from a set of choicechips, and based on those selections, modify the parameters sent to an api, thus filtering the data returned. for example, imagine you have an api that returns a list of products. you want users to be able to filter these products by category (e.g., "electronics," "clothing," "home goods"). each category will be represented by a choicechip, and when a user selects a category, only products in that category will be displayed.

*prerequisites*

*flutterflow account:* you need a flutterflow account (free or paid).
*basic flutterflow knowledge:* familiarity with creating pages, adding widgets, and basic data bindings.
*api endpoint:* you need an api endpoint that accepts filter parameters. we'll use a hypothetical example, but you can adapt it to your own api. let's assume our api endpoint is `https://api.example.com/products` and it accepts a `category` parameter: `https://api.example.com/products?cate...`.

*step-by-step tutorial*

*1. setting up the api call in flutterflow*

*navigate to api calls:* in flutterflow, go to the left sidebar and click on the "api calls" icon (looks like a plug).
*create a new api group:* click the "+ api group" button. name it appropriately (e.g., "productapi").
*add a new api call:* within the "productapi" group, click "+ add api call".
*configure the api call:*
*call name:* give the api call a descriptive name (e.g., "getproducts").
*call type:* choose the appropriate http method (usually `get` for retrievi ...
