navigationRailIndicatorOpacity property

double? navigationRailIndicatorOpacity
final

Opacity used on the NavigationBar indicator.

If undefined defaults to 24%.

The default opacity is computed from kNavigationBarIndicatorAlpha 0x3D, which is 61 giving 24% opacity. This value is the same as Flutter SDK uses in Material 2. Material 3 may often use no alpha and just different solid color hue instead. The default value of this property may be adjusted later as Flutter moves towards M3 designs. It might become 1.0.

Implementation

final double? navigationRailIndicatorOpacity;
