Theming

Need for GetX to manage the app’s theme

Creating themes in Flutter is quite straightforward. We define the colors, typography, and other theme elements inside ThemeData, the class responsible for holding the app’s theme configuration. We then provide ThemeData to the theme parameter of MaterialApp, a widget that implements the theming system in our apps. In this case, MaterialApp utilizes the configuration defined in the ThemeData and applies the theme across the application.
