In this section, we're going to create a Data Model, Data Source and a note Repository Implementation for persisting our notes locally via SQLite.

The following topics will be covered:

Before you begin

  • Make sure you have the accomplished the following guides:

    • Creating the Flutter project

    • Implementing the Domain Layer

A. External Dependencies

We'll import the necessary dependencies that we need to create our data source.

B. Creating a Data Model

We'll make a Data Model for our notes that is specific to our local SQLite Data Source.

C. Creating a Data Source

We'll implement the code for establishing connection and managing data in the local SQLite database.

D. Implementing a Repository

We'll create an implementation of the Note Repository to interact with the Data Source.
