Welcome to Flutter world

       Flutter uses the well-known AppBar to create a toolbar, but when we need a dynamic toolbar that will show content on swipe, we use the excellent SliverAppBar widget.      Both Both widgets allow you to make your application a little prettier, which is no doubt very simple in Flutter.       I have seen many questions on StackOverflow and Facebook groups about how the AppBar and SliverAppBar can be changed in terms of behavior or design.      Let's look at two tasks.      Task 1      We want to create a non-screwed AppBar , but not in the usual way.
