Ferramenta para visualização do consumo de recursos de hardware para aplicações flutter

Abstract

This Bachelor’s Thesis describes the development of a plugin that aims to help Flutter developers identify performance problems in their applications while developing them. It operates simply and directly through three key visualization aspects: frame rate rendered per second, number of Kilobytes being sent and received through the network, and amount of RAM in use and available. Based on this, the document describes what Flutter is and how it works, emphasizing the differences between packages and plugins in Flutter. Development environments for mobile, desktop, and web platforms are also covered, describing the programming languages for creating applications on each platform. The methodology for creating the plugin includes the description of each step taken during the development of the first version of the plugin, pointing out the obstacles encountered and the decisions made to solve the problems, as well as the successes and failures of the development. The results are presented in figures of two real applications and a test one, using the plugin to demonstrate how it works and how it integrates with the application that is using it. Finally, the document describes the conclusions of this work and possible future work. Key-words: Flutter. Android. Plugin. Network Monitor. FPS. Memory.
