Options to store data locally in a flutter app

There are several options to store data locally in a Flutter app, here are a few popular options:

  • Shared Preferences: This is a built-in Flutter library that allows you to easily store key-value pairs of primitive data types (strings, integers, booleans, etc.) in a secure, private location on the device.
  • SQLite: SQLite is a popular, lightweight, and open-source relational database that can be embedded into a Flutter app. The flutter_sqlite package provides a Flutter plugin for SQLite.
  • Realm IO: Its a fast alternative to SQLite. Realm’s Flutter integration automatically updates your views so you don’t have to.
  • Hive (Isar): Hive is a lightweight and easy-to-use key-value storage library that is built on top of SQLite. It allows you to store complex data structures and provides a convenient and efficient way to query and retrieve data.
  • Firebase: Firebase is a mobile development platform that provides a variety of services, including Firebase Realtime Database, which is a cloud-hosted, NoSQL database that provides real-time data synchronization and offline support.
  • File storage: You can use the dart:io library to read and write data to the file system. This approach is useful for storing larger amounts of data such as images or videos, it also allows you to store files in a specific folder on the device.
  • Object box: ObjectBox Flutter database is a great option for storing Dart objects in your cross-platform apps. Designed for high performance, the ObjectBox Flutter database is ideal or mobile and IoT devices.
  • It's worth noting that these are just a few of the options to store data locally in a Flutter app, and the best one for your app will depend on the specific needs and requirements of your app.
