Cãoteirinha: Aplicativo Flutter para Gestão da Saúde de Animais de Estimação

Abstract

The pet market in Brazil reached R$ 77.3 billion in 2024, consolidating its position as the third largest worldwide. In this context, the adequate control of the vaccination schedule represents a growing challenge for pet owners, who face difficulties in organizing vaccination records and monitoring booster dates. This paper presents the development of the mobile application Cãoteirinha, implemented in Flutter, for managing pet registration and controlling the vaccination history. The research adopted the Lean Startup methodology for validating the business model through a Lean Canvas, integrating Object-Oriented Software Engineering concepts for systematic system documentation. The development utilized object-oriented analysis and design patterns, including Use Case Diagrams, Class Diagrams, and the MVSR architecture. The Lean Canvas identified three main problems: forgetting vaccination and booster dates, disorganization of physical records, and difficulty in sharing information. The proposed solution integrates vaccination record functionalities with application and booster date control, a complete pet profile, push notifications, and digital wallet generation in PDF. The business model is aimed at pet owners aged 25-45 and animal protection NGOs. The architecture developed in Flutter allows for a cross-platform solution (iOS and Android) with a Firebase backend for data persistence and authentication. The UML diagrams document 12 main use cases and 7 fundamental domain classes. Technical validation confirms the feasibility of the implementation, while market analysis demonstrates the solution’s competitive potential. Future work includes implementing other types of animal health records, usability testing with real users, and pilot validation to confirm the business hypotheses formulated in the Lean Canvas.
