  1. Use const Widgets Whenever Possible Tip: Declare widgets as const if their properties don’t change. This helps improve performance because Flutter can reuse those widgets rather than rebuilding them. Example: dart 
const Text('Hello, World!');
  1. Leverage Flutter’s Hot Reload and Hot Restart Tip: Use Hot Reload for quick UI updates without losing the app state, and Hot Restart when you need to reset the app state. This speeds up the development process significantly.
  2. Utilize Flutter DevTools for Debugging Tip: Use Flutter’s DevTools to inspect widgets, debug layouts, track performance, and diagnose memory leaks. It’s a powerful tool to identify issues early in the development cycle. Example: You can open DevTools by running flutter pub global activate devtools and then flutter pub global run devtools.
  3. Structure Your Project with Best Practices Tip: Organize your project by separating business logic, UI, and data layers. Use BLoC or Provider for state management to make your code more maintainable and scalable.
  4. Use MediaQuery for Responsive Design Tip: To make your app responsive across different screen sizes, use MediaQuery to get information about the screen’s dimensions and apply it to your layout.
