Features

• Bidirectional — slides from top or bottom via SheetDirection.topToBottom / SheetDirection.bottomToTop
• Snap behavior — snap to edges or remain at the released position via SheetSnapBehavior.snapToEdge / SheetSnapBehavior.freePosition
• Spring physics — fine-tune mass, stiffness, damping, and velocity through SheetPhysics
• Programmatic control — open(), close(), toggle(), animateTo(height) via FlexibleSheetController
• Handle visibility — show or hide the drag handle at runtime with showHandle() / hideHandle()
• Width & alignment — optionally constrain the sheet width and align it horizontally within its parent
• Callbacks — listen to open/close state changes (onStateChanged) and continuous height updates (onHeightChanged)
• Zero dependencies — built entirely on the Flutter SDK with no external packages
