How to Use Riverpod with Repository Pattern in Flutter: A Comprehensive Guide
Repository patten is a general design pattern in software development to abstract the data layer from the rest of an application. It does this by acting as a mediator between the domain and data mapping layers, using a collection-like interface for access to domain objects. More specifically, this is useful within applications with complex business logic that may draw data from multiple sources or require joining structured data from sources in which the structure of the source data may change over time.
Below is a very simple example of how one might go about implementing the Repository pattern in a Flutter application, assuming one were fetching a list of Users from some kind of remote API.
Step 1: Define the User Model
First, define a model class that represents a user.
class User {
final int id;
final String name;
final String email;
User({required this.id, required this.name, required this.email});
factory User.fromJson(Map<String, dynamic> json) {
return User(
id: json['id'],
name: json['name'],
email: json['email'],
);
}
}
