Obtener Flutter Widgets versión histórica en Android
Una compilación de varios widgets de flutter de la documentación oficial.
This app contains a collection of several flutter widgets from the official documentation. I use this app to visualize the components, memorize them easily and later be able to replicate that behaviour in the apps I want to create. A similar app helped me a lot when I was learning ionic, so I hope this app helps other people to learn flutter widgets.
