const Positioned({
  1. Key? key,
  2. double? left,
  3. double? top,
  4. double? right,
  5. double? bottom,
  6. double? width,
  7. double? height,
  8. required Widget child,
})

Only two out of the three horizontal values (left, right, width), and only two out of the three vertical values (top, bottom, height), can be set. In each case, at least one of the three must be null.
