I want to develop an application using Flutter language. I want to make the background color of my application linear and I want to add it to the theme. There are two white circles at the top of the background and I want them to be responsive. And finally, there is an image on the opening screen, I want it to be responsive in the same way. What I want from you is to find an answer to the question "Can I make the background color linear in the theme of the application?"
I am sharing sample pictures.
