Loop attribute not working for swiper control

[takaoandrew]

I noticed that when I had loop set to off, the buttons on the swiper control still looped. I added this to fix it in a class I copied.

This is the new buildButton in swiper_control.dart.
*** means an added line

Widget buildButton(SwiperPluginConfig config, Color color, IconData iconDaga,
int quarterTurns, bool previous) {
return new GestureDetector(
behavior: HitTestBehavior.opaque,
onTap: () {
*** bool prevActivated = true;
*** bool nextActivated = true;
*** if (config.loop) {
*** } else {
*** nextActivated = config.activeIndex < config.itemCount - 1;
*** prevActivated = config.activeIndex > 0;
*** }
if (previous) {
*** if (prevActivated)
config.controller.previous(animation: true);
} else {
*** if (nextActivated)
config.controller.next(animation: true);
}
},

padding: padding,
child: RotatedBox(
quarterTurns: quarterTurns,
child: Icon(
iconDaga,
semanticLabel: previous ? "Previous" : "Next",
size: size,

))),
);
}
