How use some data all over of the app?

i want know it can be possible that when app start and got some data like user data from storage (username, token and etc), the received data reused on other page without getting it again from storage ?

more explane :
user data got from storage in profile page and same received data can be used in comment page


a common practice is to create a service provider and inject it in every component that needs same data served from service. See here
