Dart SQLite

Introduction to Dart SQLite

SQLite is a popular choice for local database storage in mobile applications due to its lightweight and self-contained nature. In the Dart ecosystem, sqflite is the most commonly used package for SQLite database operations. This package is particularly useful for Flutter applications that require efficient local data storage solutions.

Setting Up sqflite in Your Dart Project

To get started with sqflite in your Dart project, you'll first need to add the sqflite package to your pubspec.yaml file. Additionally, you may want to include path_provider to help locate the database file path.

Opening a Database Connection

Once your dependencies are set up, you can open a connection to an SQLite database. The following example demonstrates how to open a database named demo.db and create a table called users if it doesn't already exist.

Performing CRUD Operations

With the database connection established, you can now perform CRUD (Create, Read, Update, Delete) operations. Below are examples of how to insert a new user, query users, update a user, and delete a user from the database.

Conclusion

Using the sqflite package in Dart, developers can efficiently manage local databases in their Flutter applications. With basic CRUD operations, you can store and manipulate data as needed, making sqflite a powerful tool for mobile development.
