ShowCursor should use BOOL bShow and pass it in as a parameter. #831

          int ShowCursor(int bShow) => _ShowCursor(bShow);

final _ShowCursor = _user32.lookupFunction<Int32 Function(Int32 bShow), int Function(int bShow)>('ShowCursor');`

This method of hiding the mouse also does not work. It may be because this parameter is wrong. You should use BOOL bShow and pass it in as a parameter.

int WINAPI ShowCursor( In BOOL bShow);

There is no issue with the parameter.

BOOL is defined as a struct with a single int field in the metadata:

Since this struct is marked with a NativeTypeDef attribute, we simplify it by projecting it as int for ease of use.

Hi Developer, can you check why ShowCursor is not working? I passed ShowCursor(0) in dart; the mouse is not hidden!
