Custom corners - option to hide corners

[hedi-ghodhbane]

I find that this package is great, but it's missing some basic features like:

• Building Custom corners, we can pass a callBack to build a custom corner instead of showing the default one. So it would be great if this package was headless.
• Option to hide corners, i need this when i have a loading state ( for example edget detection algorithm ). I want to hide corners, then show them when loading is finished. This also can be achieved if we have the option to build custom corners

@hedi-ghodhbane The corners are already disappearing based on some logic (if the resizing is disabled by setting the minimum and the maximum sizes to the same value). You probably would like to override this behavior then?

See:

crop_image/lib/src/crop_image.dart

Lines 267 to 275 in 07a64ab

	final double maxWidth =
	constraints.maxWidth - 2 * widget.paddingSize;
	final double maxHeight =
	constraints.maxHeight - 2 * widget.paddingSize;
	final double width = _getWidth(maxWidth, maxHeight);
	final double height = _getHeight(maxWidth, maxHeight);
	size = Size(width, height);
	final bool showCorners =
	widget.minimumImageSize != widget.maximumImageSize;

This part was straightforward but the other suggestion should be discussed. There are several ways to solve that, the simpler one being just a callback with the canvas passed, the more complicated (and probably not really necessary) one would be to accept a replacement CustomPainter.
