ScaleIconSwitch class

A widget to switch between two icons with the simple material icon transition. Like the third transition here.

The animation is controlled by the animate value. firstIcon and secondIcon are properties in a IconButton so they should be some sort of icon.

If firstIcon or secondIcon are not set the other icon will just disappear. Icons are in the disabled state if they don't have there VoidCallback set

Example:

bool animate = false;

void switchIcon() {
setState(()) {
animate = !animate;
}}

ScaleIconSwitch(
 animate: animate,
 firstIcon: Icon(Icons.delete_outline),
 fsecondIcon: Icon(Icons.share_outlined),
 onFirstPressed: switchIcon,
 onSecondPressed: switchIcon,
)
