Examples

NeoRotation(
  isRotating: isLoading.value, // Using hooks
  child: PhosphorIcon(
    PhosphorIconsRegular.spinner,
    color: theme.colors.fgBrand,
    size: 24,
  ),
),

​
Properties

​
Required

​
isRotating
bool
required
Controls whether the rotation animation is active. When true, the child rotates continuously. When false, rotation stops with a smooth spring animation to the nearest complete rotation.
​
child
Widget
required
The widget to apply rotation animation to. This can be any widget including Icons, Containers, or complex widget trees.

​
Animation Behavior

​
Continuous Rotation

When isRotating is true, the widget rotates continuously at a steady pace (360° per second).

​
Spring Stop Animation

When isRotating changes from true to false, the rotation doesn’t stop abruptly. Instead, it uses a physics-based spring animation to smoothly decelerate to the nearest complete rotation (0°, 90°, 180°, or 270°).

​
Best Practices

  • Can be combined nicely with loading indicators like PhosphorIcons.spinner, PhosphorIcons.circleNotch, PhosphorIcons.arrowsClockwise etc

​
Integration Notes

  • Works seamlessly with any widget, including complex widget trees
  • The widget handles smooth transitions when isRotating state changes rapidly
