String Vault - Text Encryption & Decryption App

SecureVault is a Flutter application designed to provide users with an easy and secure way to encrypt and store their text data.

Features

Encrypt and Save: Users can encrypt a string and store it locally in a secure SQLite database.
Decrypt and Display: Users can decrypt the stored encrypted strings and display them on the user interface.
List View: Multiple encrypted strings can be stored, and they are displayed in a list view using a ListView Builder.
Copy and Delete: Each item in the list view has buttons to copy the encrypted value of the string and delete the entry.

This app utilizes the following Flutter packages:

sqflite: A SQLite plugin for Flutter, providing a local database to store encrypted strings.
encrypt: A library for encryption and decryption, used to secure the stored data.
provider: A state management library for Flutter, separating business logic and UI.
