bottomOpacity property

double bottomOpacity
final

How opaque the bottom part of the app bar is.

A value of 1.0 is fully opaque, and a value of 0.0 is fully transparent.

Typically, this value is not changed from its default value (1.0). It is used by SliverAppBar to animate the opacity of the toolbar when the app bar is scrolled.

Implementation

final double bottomOpacity;
