![]() ![]() In this article we’ll look at Moor, but the approach that these two packages take in abstracting SQLite is fairly similar. These abstractions can make a SQLite database easier to use, while still retaining a lot of the benefits of SQLite.įloor and Moor are fairly popular examples of this approach. That’s why there are so many solutions that abstract some of the functionality from SQLite into more easily used functionality. ![]() □ĭirectly using SQLite to manage your application database can be quite powerful but also unwieldy. This would be incredibly fast but would open you up to some weird bugs if you weren’t a programming genius. You can store your data in a JSON file and handle the serialisation and deserialisation yourself. Individually tailored data storage - while this option is not technically a database, you don’t have to use the above solutions. ![]() MongoDB is an example of a NoSQL database. They are lightning-quick and handle huge unstructured pieces of data very well. A schema is not enforced as is the case with a relational database. NoSQL - these databases store data as documents. SQLite is an example of a relational database. They don’t just store data but also the relationships between the data. Relational - these are the databases in the traditional sense. They typically fit into these three categories: There are a lot of options out there today when it comes to databases in your application. But which is the best database for Flutter? Lewis Cianci checks it out. String path = join(documentsDirectory.path, "database_name.No matter who you are or what you do, sooner or later you’re going to need to store data in your app and then retrieve it later. Io.Directory documentsDirectory = await getApplicationDocumentsDirectory() Static final DatabaseHelper _instance = new DatabaseHelper.internal() Import 'package:path_provider/path_provider.dart' Ideally, it should be used with some kind of Dependency Injection technique. This class is going to be used throughout the app’s lifecycle. Path_provider: ^0.5.0+1 #helper package used by database helper class to get the database file Create a Database Helper Class Depend on SQFliteĪdd the following dependencies to pubspec.yml and run “flutter packages get” command in the terminal.ĭependencies: sqflite: ^1.1.0 #sqflite packageįlutter_simple_dependency_injection: ^1.0.1 #to perform dependency injection In this article, we will be demonstrating an example (TODO App) of using the SQFlite plugin in the Flutter application. If you are new to SQLite and SQL statements, go ahead & learn the basics of SQLite from SQL Tutorial The plugin is well-maintained and is recommended by the Flutter team as well. However, using the SQFlite plugin, one can access the SQLite database on both Android & iOS. Why use the SQFlite plugin?įlutter does not provide a built-in abstraction for accessing the SQLite Database. It supports both the native platforms i.e Android & iOS. Both Android & iOS relies heavily on SQLite. SQLite is the world’s most used database and is used in almost every connected device. SQLite does not have a separate server process which means that it essentially stores the data in a file (also known as an embedded mode). SQLite is an open-source relational database. We are going to demonstrate it on a TODO list example. In this article, we are going to discuss how to set up a local SQLite database in a Flutter app. To be precise, there is no such database method available for Flutter but one can integrate the SQLite database system to the Flutter app using SQFLite plugin. But, when you jump to the next step that is creating a Database, you might get stuck. Starting with the configuration and architecture of a Flutter app is a straightforward process. With its cross-platform features and easy to implement methods, Flutter has attracted the interest of many developers. The soaring technology trend in the mobile app industry is nothing but Flutter, a cross-platform SDK launched by Google. ![]()
