+### Simple rolling animation with loading
+To use the loading animation, you simply have to return a future in `onChanged` or `onTap`.
+You can alternatively control the loading manually with the `loading` parameter.  
+Hence, to disable the loading animation, `loading: false` must be set.
+
+```dart
+AnimatedToggleSwitch<int>.rolling(
+  current: value,
+  values: [0, 1, 2, 3],
+  onChanged: (i) {
+    setState(() => value = i);
+    return Future.delayed(Duration(seconds: 3));
+  },
+  loading: false, // for deactivating loading animation
+  iconBuilder: iconBuilder,
