Proposta de arquitetura orientada a packages para aplicativos flutter

Abstract

The growth of the mobile device industry combined with the users' increased demand for quality and speed of development makes it necessary to use software architectures that consider every aspect of mobile development. From this need emerges architectures such as microfrontends, which attribute independence and modularity to functionality by treating it as an application. However, the microfrontend architecture has no formalization or theoretical referential, implying different forms of implementation by the companies that use it and, consequently, inconsistencies in the final product. This work proposes a Packages Oriented Architecture proposal as a formalization of the microfrontend architecture for the Flutter development environment. For this approach, the microfrontends architectures implemented in the applications of the companies Nubank, Banco Votorantim, Unico and IKEA were analysed to study the fundamental elements common to each implementation. From the study and standardization of these elements, the proposed architecture establishes criteria and formalizes the microfrontend architecture providing modularization, system scalability and independence among functionalities. Finally, an application that implements the proposed architecture was developed to validate its functioning.
