What is serialization in flutter?

use jsonEncode() and jsonDecode() from ‘dart:convert’ to serialize JSON data . create model classes with fromJson() and toJson() for all domain-specific JSON objects in your app. add explicit casts, validation, and null checks inside fromJson() to make the parsing code more robust.

json_serializable: This is provided to a Dart build system. It generates code when it finds annotated members in a class defined with json_annotation . json_annotation: It defines the annotation used by Json_serializable to create JSON serialization, deserialization type of code.26 Haz 2021

JSON serialization with code generation means having an external library generate the encoding boilerplate for you . After some initial setup, you run a file watcher that generates the code from your model classes.

If you intend to save user data to the shared preferences or local storage in your Flutter application, you will need to serialize it manually. This is because both methods only support a limited selection of primitive object types and your object will probably not fall into any category.

To deserialize a list of objects from JSON in flutter follows the below steps:
