What is Navigation Rail?

Think of the Navigation Rail as a vertical sidebar for navigating your app. It’s always visible on larger screens, making it easy for users to jump between sections. Unlike a drawer (which you have to open) or a bottom bar (that might feel out of place on a big screen), the Navigation Rail is sleek, functional, and always within reach. 🚀

How Does Navigation Rail Work?

The Navigation Rail is pretty easy to set up. It lives inside a Scaffold and usually pairs with a Row to create a layout where the rail sits on one side and your main content takes up the rest.

Key Ingredients:

• NavigationRail: This is your main widget.

• NavigationRailDestination: Each destination has an icon and an optional label.

• selectedIndex: Tracks which destination is currently active.

• onDestinationSelected: Updates the active destination when a user clicks on it.

2. Style Labels: Adjust the selectedLabelTextStyle and unselectedLabelTextStyle for a unique look.

3. Tweak Icons: Modify the selectedIconTheme and unselectedIconTheme to match your design.

4. Add Extra Actions: Want a settings button at the bottom? Use the leading or trailing properties.

5. Align Items: Use groupAlignment to control the vertical alignment of items in the rail.
