JSON Parsing in Flutter
Nowadays, we don’t have a single app that is not connected to the internet one way or another, and making API calls and fetching the data is very common.

For simplicity, we will see the get request and parse its response. I am going to use the flickr public API for demo purposes we will make an image search request and parse the response.
Add dependency for http package to your pubspec.yaml, it will enable you to use get method from http.

The model will look something like
Now, you can use this model in a simple way as shown below
