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.

Persist data in Local Database of your Android or iOS device with Sqlite and Sqflite plugin. 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.
