A Simple Flutter project for illustrating basic functionalities based on some features. It demonstrates responsive design and state management. The app allows users to fill out a registration form and view the submitted details on a separate screen.

• Responsive Design: The app uses SafeArea, Expanded, MediaQuery, and LayoutBuilder to adapt the UI based on the screen size. It has different layouts for wide and narrow screens.

   // .... existing codes
      body: SafeArea(
          child: LayoutBuilder(
              builder: (context, constraints) {
                  // If the screen width is greater than 600, use WideLayout; otherwise, use NarrowLayout.
                  if (constraints.maxWidth > 600) {
                      return WideLayout();
                  } else {
                      return NarrowLayout();
                  }
              },
          ),
      ),
  // .... existing codes

• State Management: The app uses the Provider package for state management. The registration data is managed using a ChangeNotifier model.

      // .... existing codes
      ChangeNotifierProvider(
          create: (context) => RegistrationModel(),
          child: MyApp(),
      ),
      // ... codes

• Form Validation: The registration form includes fields for first name, middle name, last name, gender, email address, phone number, and country of birth.
