Layouts like ListTile (A Single fixed-height row that typically contains some text as well as a leading or trailing icon), Stepper (A material steeper widget that displays progress through a sequence of steps), Divider (A one logical pixel thick horizontal line, with padding on either side) and lots more. With Flutter you can also develop different type of awesome things like simple dialog (This can provide additional details or actions about a list item. For example they can display avatars icons clarifying subtext or orthogonal actions), alert dialog (This are urgent interruptions requiring acknowledgement that inform the user about a situation. The Alert Dialog widget implement this component), bottom sheet (This slide up from the bottom of the screen to reveal more content. You can call showBottomSheet() to implement a persistent bottom sheet) and lots more.
