Database

The app uses the Isar database to store notes locally. Isar is a high-performance database designed for Flutter and Dart.

Initialize Database

To initialize the Isar database, ensure you have the following setup in your code:

import 'package:isar/isar.dart';
import 'package:path_provider/path_provider.dart';
import 'dart:developer';
import 'dart:io';

class NoteDatabase extends ChangeNotifier {
  static late Isar isar;

  static Future<void> clearDatabase() async {
    final dir = await getApplicationDocumentsDirectory();
    final dbDir = Directory(dir.path);
    if (await dbDir.exists()) {
      dbDir.deleteSync(recursive: true);
    }
  }

  static Future<void> initialize() async {
    try {
      await clearDatabase();
      final dir = await getApplicationDocumentsDirectory();
      log('Database directory: ${dir.path}');
      isar = await Isar.open([NoteSchema], directory: dir.path);
      log('Database initialized successfully');
    } catch (e) {
      log('Error initializing database: $e');
      rethrow;
    }
  }
}

Schema Definition

Ensure your schema is defined correctly:

import 'package:isar/isar.dart';

// Generates the file
// Run dart run build_runner build
part 'note.g.dart';

@Collection()
class Note {
  Id id = Isar.autoIncrement;
  late String text;
}
