HiveDb - Hive Database Handler for Flutter

This Flutter project provides a reusable, singleton class, HiveDb, to handle Hive database operations. The class manages the initialization, configuration, and CRUD operations on a database, allowing developers to define their own data models and manage user accounts, pizzas, and invoices dynamically.

Features

Singleton Pattern: Uses a single database instance throughout the app.
Initialization: Sets up the database and opens necessary boxes.
Table Management: Allows custom table definitions for box creation.
CRUD Operations: Provides methods for creating, reading, updating, and deleting records.
User Management: Supports user insertion and retrieval with validation.
Invoice Management: Saves invoices and generates the next invoice number.

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:

dependencies:
  flutter:
    sdk: flutter
  hive: ^2.0.0
  hive_flutter: ^1.1.0
  path_provider: ^2.0.10

dev_dependencies:
  build_runner: ^2.4.11
  hive_generator: ^2.0.1

Installation

Clone the repository or copy the HiveDb class into your Flutter project.
Run the build_runner command in your terminal:

dart run build_runner build

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

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await HiveDb().initializeDatabase();
  runApp(MyApp());
}

Notice

You can easily customize the database structure by modifying the user, pizza, and invoice classes as needed. This makes HiveDb suitable for a variety of applications, from simple projects to more complex systems with unique data requirements.
