NASA Space Lines is a space exploration application developed with Flutter and Dart. The project allows users to explore different space destinations, view information about planets and the International Space Station (ISS), access NASA's Astronomy Picture of the Day (APOD), and calculate how much they would weigh on different celestial bodies. The application was developed as a practical project to improve mobile and web application development skills, API integration, UI development, state management, and problem-solving with Flutter. The application allows the complete management of events, participants, locations, tickets and registrations, offering operations for creating, querying, updating and removing data through organized endpoints. The main purpose of the API is to provide a simple and efficient framework for controlling information related to the organization of events.
