Using sqflite databases

In this section, we'll create a new project, add the sqflite dependencies, and create our database through a SQL raw query. Then, we will test the database we've created by adding some mock data and printing it in the debug console. This will require a few methods to insert and retrieve data from the database.

Creating an sqflite database

Let's create a new Flutter project from your editor. We can call it shopping. Follow the steps given here:

  1. As sqflite is a package, the first step to perform in order to be able to use it in our project is adding the dependency in the pubspec.yaml file.
