Secure Notes

Introduction

The app where you can add your own notes. It should behave as normal notes app where you can add, modify, remove old notes, but the app should be secure. Being secure means that the notes should only be accessible through the app, and only after biometric authentication.

Packages: sqflite package.

Add sqflite package, so your notes will be saved, even when app reloads. When app loads it should get notes from database.

class Database {
Database _db;

    Future create() async {
        Directory path = await getApplicationDocumentsDirectory();
        String dbPath = join(path.path, "database.db");

        _db = await openDatabase(dbPath, version: 1);
    }
}

Database class should also have CRUD methods like getAllNotes, deleteAllNotes, addNote, deleteNote, updateNote.
