  • Fix DraggableScrollableSheet drag speed is off #179102
  • In this PR:
    • Fix the sheet position so that it will follow the pointer, even when dragging mouse beyond the window then returns inside.
    • Some improvement for coding convention:
      • declare minChildSize and maxChildSize const(s) then use them in the hardcoded positions
      • move _isOnDesktopAndWeb out of Grabber, so it's easier to see Grabber widget purpose when reading the code
Demo
