HTTP API calling in flutter


In the mobile app development lifecycle, communicating with the server(via API) to fetch or store data is one of the basic needs. In today’s blog let’s check HTTP API calling in flutter.

Fetching data from the internet is very important for most applications.

First of all, let’s understand API.

Application programming interface (API)

An application programming interface (API) is an interface that defines interactions between multiple software applications or mixed hardware-software intermediaries.

It defines the kinds of calls or requests that can be made, how to make them, the data formats that should be used, the conventions to follow, etc.

Flutter provides tools for API calling such as HTTP package.

Please follow below steps for HTTP API calling in flutter

Step1: Create a flutter project.

Step2: Add the below dependencies in pubspec.yaml file

Now, run the command “flutter pub get” to download the dependencies.

Step3: Let’s create a class for API calling.

Step4: Now, create a model class to store the API data.

Step5: Then, call the api method from your main.dart class.

Step6: Now, we can display our data in the form of a list. Please check below the complete code for main.dart class.

Finally, you can run the code, and see the below results.

For more details and methods you can refer the official doc of flutter here.
