# SqlDb - SQLite Database Handler for Flutter

This Flutter project provides a reusable, singleton class, `SqlDb`, to handle SQLite database operations using the `sqflite` package. The class manages the creation, initialization, and CRUD operations on a database, allowing developers to define their own table schemas dynamically.

## Features

- **Singleton Design Pattern**: Ensures only one instance of the database is used throughout the app.

- **Database Initialization**: Automatically initializes the database and creates tables based on user-defined schemas.

- **Flexible Table Management**: Add custom table definitions that will be used to create tables when the database is initialized.

- **CRUD Operations**: Includes methods for creating, reading, updating, and deleting records.

- **User Management**: Allows inserting and retrieving users, with support for username and password validation.

- **Invoice Management**: Supports saving invoices and generating the next invoice number for a user.

  

## Getting Started

### Prerequisites

Ensure you have Flutter installed and set up on your machine. You will also need to include the following dependencies in your `pubspec.yaml` file:

```yaml

dependencies:

  flutter:

    sdk: flutter

  sqflite: ^2.0.0+4

  path: ^1.8.3

```

### Installation

Clone the repository or copy the SqlDb class into your Flutter project.

Initialize the database in your main application file. You can do this using an anonymous object:

```dart

Future main() async {

  WidgetsFlutterBinding.ensureInitialized();

  await SqlDb().initializeDatabase();

  runApp(MyApp());

}

```

## Notice

You can easily customize the database structure by modifying the table definitions in the `_onCreate` method. This makes `SqlDb` suitable for various applications, from simple apps to complex systems with unique data needs.
