The entity class will represent a database table Columns. Tthe @entity marks the class as a persistent class and you need to add a primaryKey

// entity/student.dart

 import 'package:floor/floor.dart';

 @Entity(tableName: 'students')
 class Student {
   @primaryKey(autoGenerate: true) 
   final int id;

   final String name;
   final Float grade;
   Person(this.id, this.name, this.grade);
 }

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking Android and iOS applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).

Moor (Room for Flutter) – Foreign Keys, Joins & Migrations – Fluent SQLite Database

Moor (Room for Flutter) – Foreign Keys, Joins & Migrations – Fluent SQLite Database. Moor is a powerful library for using an SQLite database from your Flutter apps by writing pure Dart code. Your app's database will probably have more than one table. To make joins safe, it's a good idea to use foreign keys. Adding new columns or whole tables requires you to provide a migration to let the previous versions of the database upgrade themselves.

Hive (Flutter Tutorial) – Lightweight & Fast NoSQL Database in Pure Dart

Hive (Flutter Tutorial) – Lightweight & Fast NoSQL Database in Pure Dart. Hive is a lightweight, yet powerful database which is easy to develop with and it also runs fast on the device. Unless you absolutely need to model your data with many relationships, in which case you should probably use SQLite, choosing this pure-Dart package with no native dependencies (it runs on Flutter Web!) can be the best option.

Moor (Room for Flutter) – Advanced Queries & DAOs – Fluent SQLite Database

Moor is a powerful library for using an SQLite database from your Flutter apps by writing pure Dart code. To separate the queries dealing with tasks (and in the future, with comments and habits), we can use data access objects (DAOs). The functionality of the queries will remain unchanged, they will only be moved to a new and cleaner place.
