![]() The database instance has access to methods such as insert(), update(), query(), and delete() for performing the CRUD operations on the database. ![]() Now let’s get back to the DatabaseHelper class and write the DB methods to do the CRUD operations.Īn instance of the database class is assigned to the db property of the DatabaseHelper class in the initDB() method. import 'package:flutter/material.dart' Ĭlass SqliteDemoApp extends StatelessWidget build(BuildContext context) įor conversion between instances of User class and Map objects used by the SQLite DB, the methods toMap() and fromMap() have been defined. Open a simulator device or connect a real device to your system and start the app using the following command: flutter runįor this app, you’ll need a stateful widget for managing the state of the form locally. For this article, you’ll need the sqflite package for using the SQLite database. So fire up your favorite text editor and let’s get cracking! Create a new Flutter projectįirst, open up your terminal and create a new Flutter project: flutter create sqlite_demo In this guide, we’ll show you how to create a simple Flutter app that accepts few details of a user using a form and stores it in the database. ![]() That means everything we store in the database will stick around even if the user restarts the application or the device itself. The SQLite database we’ll use in this Flutter tutorial is a persistent data store that preserves the data even after the application is closed. Persistent data in local storage has been around since the early days of mobile app development. One of the biggest factor that defines whether an app is performant is how it fetches and stores data locally. At first, you will have to call countTable() from the main() function. Here countTable()function basically counts the number of tables in the database. How to persist data in Flutter using SQLite To initialize an SQLite database in Flutter, you will have to create an SQLiteDB class as shown below. Reach out to me on LinkedIn or Instagram. from the command line with Flutter by using below command: flutter packages get. I work with React and NodeJS to build customer-centric products.
