Color of thumb circle not equals underlying color about flutter_circle_color_picker

[mavanpee]

I resolved this on my own download. It's because the underlying gradient isn't drawn correctly, as you can see the red section is much larger than the blue, but they should be equal in length. It's a lot more noticeable if you increase the stroke width to something like 20+.

Luckily it's fixed with one line change.

In the _CirclePickerPainter class in flutter_circle_color_picker.dart, the class responsible for drawing the circle and it's gradient, change the createShader lines as follows (commented our old line in favour of the new one). Note that to avoid conflicts, I had to rename the "center" variable in this class to be called "circleCenter" instead. Here's the change:

        final sweepShader = sweepGradient.createShader(
            // Rect.fromLTWH(0, 0, radio, radio),                  // --> OLD line
            Rect.fromCircle(center: circleCenter, radius: radio),  // New Line; changed "centre" to "circleCenter"
        );

@mavanpee Thank you! Would you make PR to fix this?

Hehe.. I'll be completely honest with you, one of the reasons I was being so descriptive in my post is because I have absolutely no idea how to do a PR myself. I've never really used github before.
