curved_navigation_rail

Description:

curved navigation rail

curved_navigation_rail #
pub.dev ->
A Flutter package for easy implementation of curved navigation rail. Designed to be a direct drop-in replacement for NavigationRail.
This is a fork of the curved_navigation_bar package. Thank you to the developers of that package for inspiration. Now the same curved theme can consistently be applied in adaptive layouts!

Retaining the same example as curved_navigation_bar:

Add dependency #
dependencies:
curved_navigation_rail: ^2.0.1 #latest version
copied to clipboard
Easy to use #

See minimal_example.dart in the examples

Attributes #
destinations: List of NavigationRailDestinations
selectedIndex: index of NavigationRail, can be used to change current index or to set initial index
color: Color of NavigationRail, default Colors.white
buttonBackgroundColor: background color of floating button, default same as color attribute
backgroundColor: Color of NavigationBar's background, defaults to the context theme's scaffoldBackgroundColor
onDestinationSelected: Function handling taps on items, takes an int of the selectedIndex
animationCurve: Curves interpolating button change animation, default Curves.easeOutCubic
animationDuration: Duration of button change animation, default Duration(milliseconds: 600)
width: Width of NavigationRail, min 0.0, max 75.0
letIndexChange: Function which takes page index as argument and returns bool. If function returns false then page is not changed on button tap. It returns true by default\
Examples #


minimal_example.dart - the bare minimum.


change_page_programatically.dart - example of changing navigation rail item using a button on the page.


navigation_rail_dropin.dart - direct replacement for NavigationRail. Just replace NavigationRail with CurvedNavigationRail!


navigation_rail_dropin_inverted.dart - extended example of navigation_rail_dropin.dart showing an inverted navigation rail, for right to left directionalities. (TO BE IMPLEMENTED).


Road map #

Add support for Right-To-Left directionality, i.e. invert the CurvedNavigationRail when placed on the right of the screen.
Add support for displaying text with the icon, and subsequently support for NavigationRailLabelType as a parameter input as used in NavigationRail.
Add parameter for height and alignment, to allow for greater customisation than just spaced evenly along the entire height.
Add support for adaptive layout, so that the rail extends to a drawer at a given width threshold.
