toolbarOpacity property

double toolbarOpacity
final

How opaque the toolbar 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 toolbarOpacity;
