Destination class

A model class representing a navigation destination in a drawer or navigation bar.

Each destination consists of:

• A label displayed next to or below the icon
• An icon shown when the destination is not selected
• A selectedIcon shown when the destination is selected

Example usage:

final destinations = [
  Destination(
    'Profile',
    profileOutlinedIcon,  // Unselected state icon
    profileFilledIcon,    // Selected state icon
  ),
  Destination(
    'Settings',
    settingsOutlinedIcon,
    settingsFilledIcon,
  ),
];

This class is designed to work with NavigationDrawer. The icons typically form a pair where one is the outlined version and the other is the filled version of the same icon.

Example usage with NavigationDrawer:

final destinations = [
  Destination(
    'Profile',
    Icon(Icons.person_outline),  // Outlined version for unselected state
    Icon(Icons.person),         // Filled version for selected state
  ),
  Destination(
    'Settings',
    Icon(Icons.settings_outlined),
    Icon(Icons.settings),
  ),
];

NavigationDrawer(
  destinations: destinations.map((d) =>
    NavigationDrawerDestination(
      icon: d.icon,
      selectedIcon: d.selectedIcon,
      label: Text(d.label),
    ),
  ).toList(),
)

Common icon pairs:

• Profile: Icons.person_outline and Icons.person
• Settings: Icons.settings_outlined and Icons.settings
• Home: Icons.home_outlined and Icons.home
• Notifications: Icons.notifications_outlined and Icons.notifications
