Themes are used to share color, font and design styles in your apps. By default, Flutter provides us with a default theme when we use the MaterialApp. This theme has the light and dark version. Currently, it is set to the light theme. It has a primary color of blue as seen in the AppBar, BottomNavigation bar and the FloatingActionButton.
