The Calculator App is an application that allows users to enter a specific code to access a hidden screen. In the hidden screen, users can hide images from their device's gallery and save selected images within the application they can also unhide the images if they want.
The project consists of multiple Dart files, organized as follows:
main.dart: This serves as the entry point for the application.
-
FirstScreen.dart: This file contains the logic and user interface for the initial screen of the app. -
Hide.dart: Here, you'll find the implementation for the hidden screen, where users can manage their gallery images.
-
Database.dart: We use the Sqflite database to enable offline functionality and enhance app performance. -
Photo.dart: This file defines the data model for photos used within the application.
We opted for the Sqflite database for its offline capabilities and speed. This choice ensures that the app can function efficiently without relying on an internet connection.
The Calculator App relies on several packages to facilitate its functionality:
-
math_expression: Used to evaluate mathematical expressions. -
image_picker: Enables users to pick images from their device's gallery. -
sqflite: Provides the database functionality for offline data storage. -
path_provider: Used to access the device's file system path. -
typed_data: Utilized for working with low-level binary data.
Please refer to the respective Dart files and package documentation for more details on their usage and implementation within the Calculator App.
