Study Notes

Front-End of Application

Flutter is an open-source software development kit that enables smooth and easy cross-platform mobile app development.
Flutter allows building high-quality natively compiled apps for iOS and Android quickly, without having to write separate code for each platform.

Advantages of Flutter

One codebase for all platforms, reducing development time, cost, and enabling faster app launch.
"It is all Widgets" principle offers countless possibilities, creating great visuals for the app.
Rich libraries, using the Sika Graphics Library, which is a fast and mature open-source graphics library, providing a quick and smooth app experience.
Fast testing with hot reloads, making app development quicker and allowing for more experimentation with the code and fixing bugs on the go.

Mobile Application Development Environment

The mobile application is developed using the Flutter framework and Dart.
The development environment includes necessary dependencies such as Firebase plugins.

Firebase CLI

Firebase CLI is a set of commands that can be run in the command line interface (CLI) to connect Firebase with Flutter, ROS2, or any other platform.
Allows logging in with the account created on the Firebase console website.
Lists the projects associated with the logged-in account.

Firebase Overview

Firebase is a cloud database that offers various services like authentication and cloud Firestore.
Cloud Firestore allows uploading data and reading from it.
In the application, user input locations are stored in the database, and the drone retrieves this data and moves accordingly.

User Interface Implementation

The UI design follows Design principles for a cohesive user experience.
The app includes screens for login, signup, waypoints input, and home navigation.
Video data is transmitted in real-time to the app for display.

Mobile Application Functionality

The mobile application has a user-friendly interface designed using Flutter.
The app includes a splash screen, login and signup screens, home page, waypoints page, and video streaming screen.
Firebase is used for authentication, cloud Firestore, and other services.

Authentication and Security

The application ensures secure access via Firebase authentication mechanisms.
User authentication is handled securely through login and registration processes.
Data security is ensured through Firebase's data-at-rest security.

System Integration

The overall system architecture integrates the simulated drone and the mobile application.
Components interact through the user initializing the Flutter app to send waypoints to Firebase, which acts as a cloud to save exchanged data between Flutter and ROS 2.
