Dart is awesome, but defining a "model" can be tedious. We may have to:

define a constructor + the properties
override toString, operator ==, hashCode
implement a copyWith method to clone the object
handling de/serialization
Implementing all of this can take hundreds of lines, which are error-prone and affect the readability of your model significantly.

Freezed tries to fix that by implementing most of this for you, allowing you to focus on the definition of your model.

In this lecture i will teach you how to create model with freezed in flutter.
