# Serializing JSON Manually in Flutter

Turn API responses into Dart objects you can actually work with

## What this does

Your app gets data back from a server as JSON, and you need it as real Dart objects with named properties. This writes the model class with the code that converts each way, using Dart's built-in conversion. Reach for it when the data is simple enough to map by hand.

### Top 3 things it does for you

- Write a model class that reads JSON
- Turn an object back into JSON
- Map API field names onto class properties

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Serializing JSON Manually in Flutter

This creates model classes with the two methods that do the conversion: one that builds an object from JSON, and one that turns an object back into JSON. It uses `dart:convert`, which ships with Dart.

It is meant for the case where you are mapping JSON keys to class properties by hand, on data structures simple enough that doing it manually makes sense.
