Research direction

Look at the simple_chat component's theme files, likely in a directory like packages/simple_chat/lib/theme/. Examine the current default theme to understand its structure. The goal is to create a more visually interesting custom theme that showcases Flutter's theming capabilities. Check for existing examples of custom themes in the project to follow the same patterns. Test the changes by running the simple_chat example to see the new appearance.
