Usage:

// Automatic platform-adaptive selection
showAdaptiveModalSheet(
  context: context,
  // No SheetViewport is required here
  builder: (context) => Sheet(
    child: Container(height: 300),
  ),
);

// Standard modal
showModalSheet(
  context: context,
  builder: (context) => Sheet(...),
);

SheetScrollHandlingBehavior - #284

SheetScrollHandlingBehavior has been added to provide precise control over scroll gestures within scrollable widgets inside a sheet.

Usage:

Sheet(
  scrollConfiguration: SheetScrollConfiguration(
    scrollHandlingBehavior: SheetScrollHandlingBehavior.onlyFromTop,
  ),
  child: ListView(...),
)

Available options:

• always: The sheet always takes precedence over scrollable widgets for gesture handling, allowing it to move upward/downward in response to overscroll gestures. This option maintains the existing sheet behavior (used by default).
• onlyFromTop: The sheet behaves the same as always mode when scrolling starts from the top position (ScrollPosition.pixels == 0.0). Otherwise, the scrollable widget handles the gesture exclusively, preventing the sheet from moving upward/downward in response to overscroll and enabling the scrollable widget to perform overscroll-driven behaviors such as the bouncing animation by BouncingScrollPhysics. This option was introduced to match native sheet behavior on iOS and Android platforms.
