A Flutter modal bottom sheet driven by spring physics (not a static curve/tween), with a ready-made Material Expressive visual style included.

0.0.1

Initial release.

• showSpringBottomSheet — shows a modal sheet anchored to the bottom of the screen with a spring-driven animation (enter: expressive spatial spring, exit: fast standard spring) using the motor package.
• SpringSheetRoute — a custom PopupRoute implementation that supports:
  • interactive dragging that drives the route animation directly,
  • fling velocity from a released drag carried into the open/close simulation,
  • overdrag resistance when the sheet is dragged past its fully-open position,
  • automatic close threshold based on drag velocity or final resting position,
  • an isDismissable option to disable closing via drag, scrim tap, and the back button,
  • keyboard-safe padding and accessibility/semantics labels.
• ThingExpressiveSheet — a ready-to-use wrapper widget with a Material Expressive style: a rounded card, an optional drag indicator (grabber), and maximum size constraints.
