autosqflite 1.0.0

An automatic SQLite database helper for Dart/Flutter that handles table creation and schema updates automatically.

AutoSqfLite

A simple, automatic SQLite database helper for Flutter that handles table creation and schema updates dynamically. No more writing CREATE TABLE statements or managing migrations manually!

Features

• 🚀 Automatic table creation from Dart objects
• 📊 Dynamic schema updates when new fields are added
• 🔄 Automatic type mapping between Dart and SQLite
• 💾 Simple CRUD operations
• 🛠 Zero configuration required
• 🎯 Type-safe operations

Installation

Add this to your package's pubspec.yaml file:

dependencies:
  autosqflite: ^1.0.0

Usage

Basic Setup

// Create an instance of AutoSqfLite
final db = AutoSqfLite(databaseName: 'my_app');

Creating Models

class Todo {
  final int? id;
  final String title;
  final bool completed;
  final DateTime createdAt;

  Todo({
    this.id,
    required this.title,
    required this.completed,
    required this.createdAt,
  });

  // Convert to Map for database operations
  Map<String, dynamic> toMap() {
    return {
      'id': id,
      'title': title,
      'completed': completed,
      'createdAt': createdAt,
    };
  }

  // Create from Map
  factory Todo.fromMap(Map<String, dynamic> map) {
    return Todo(
      id: map['id'],
      title: map['title'],
      completed: map['completed'] == 1,
      createdAt: DateTime.fromMillisecondsSinceEpoch(map['createdAt']),
    );
  }
}

CRUD Operations

// Insert
await db.insert('todos', todo.toMap());

// Get all records
final todos = await db.getAll('todos');

// Get single record
final todo = await db.get('todos', 1);

// Update
await db.update('todos', todo.toMap(), 1);

// Delete
await db.delete('todos', 1);

Automatic Schema Updates

AutoSqfLite automatically handles:

• Table creation when you first insert data
• Adding new columns when your model evolves
• Type mapping between Dart and SQLite

// Original model
class User {
  String name;
  int age;
}

// Later, add new fields - AutoSqfLite handles it automatically!
class User {
  String name;
  int age;
  String email;    // New field
  bool isActive;   // New field
}

Supported Types

AutoSqfLite automatically maps between Dart and SQLite types:

Dart Type	SQLite Type
int	INTEGER
double	REAL
String	TEXT
bool	INTEGER
DateTime	INTEGER

Example

Here's a complete example using AutoSqfLite in a Todo app:

class TodoService {
  final AutoSqfLite _db;
  static const String tableName = 'todos';

  TodoService() : _db = AutoSqfLite(databaseName: 'todo_app');

  Future<void> addTodo(Todo todo) async {
    await _db.insert(tableName, todo.toMap());
  }

  Future<List<Todo>> getAllTodos() async {
    final maps = await _db.getAll(tableName);
    return maps.map((map) => Todo.fromMap(map)).toList();
  }

  Future<void> updateTodo(Todo todo) async {
    await _db.update(tableName, todo.toMap(), todo.id!);
  }

  Future<void> deleteTodo(int id) async {
    await _db.delete(tableName, id);
  }
}

Additional Features

• Automatic handling of boolean values (converts to 0/1 for SQLite)
• DateTime conversion to milliseconds for storage
• Null-safe operations
• Automatic table existence checking
