Take a look at the documentation for the CupertinoPickerDefaultSelectionOverlay class.

By passing it to CupertinoPicker you can disable the margin, but it'll also lose the rounded corners.

  CupertinoPicker(
    selectionOverlay: const CupertinoPickerDefaultSelectionOverlay(
      capStartEdge: false,
      capEndEdge: false, 
    ),
    // other parameters,
  )
