RefreshProgressIndicator class
An indicator for the progress of refreshing the contents of a widget.
Typically used for swipe-to-refresh interactions. See RefreshIndicator for a complete implementation of swipe-to-refresh driven by a Scrollable widget.
The indicator arc is displayed with valueColor, an animated value. To
specify a constant color use: AlwaysStoppedAnimation<Color>(color)
.
