![]() ![]() If you encounter issues running the project on iOS, run pod install & pod update inside a Terminal window at the project root. The starter project provides the interface and some logic for the movie tracking app.īuild and run the starter project. If you get a ‘Packages get’ has not been run message, open the pubspec.yaml file and run the get dependencies for Flutter command. You can also use VS Code, but the instructions in this tutorial will be using Android Studio. Then, open it in Android Studio 3.5 or later. Getting Startedĭownload the starter project by clicking the Download Materials button at the top or bottom of this tutorial. You should also have knowledge of using Android Studio with Flutter, which you can learn about in this Getting Started with Flutter in Android Studio screencast. If you’re new to Flutter, read through the Getting Started With Flutter tutorial. Note: This tutorial assumes you’re already familiar with the basics of Flutter development. Perform migrations and schema versioning in your database.Insert, delete, update data in the database.Use the sqflite Flutter plugin to interact with an SQL database.In this tutorial you’ll write an application called Cinephile to track movies you’ve watched. Now, you’re facing the dilemma of answering these questions accurately. They say yes, and you’re excited until they want to know when you last watched it and how many times you’ve watched it. Say you wanted to watch one of your favorite movies and ask your friend to join you. It allows you to to do everything you know and love with SQL – perform joins on tables, migrations, updates and much more. SQLite is a variation of the SQL database language that allows you to save your data in a relational database and persist that data between app sessions. But as your data grows more complex and more interdependent, you’ll need to use a more formal data storage system, like SQLite. If the data is simple enough, you might be able to get away with using a key value storage system. The database instance has access to methods such as insert(), update(), query(), and delete() for performing the CRUD operations on the database.You’ll often find that you need to save data in your Flutter applications between app launches. 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. How to persist data in Flutter using SQLite Reach out to me on LinkedIn or Instagram.
