Chris W. is 100% correct, using a vector editor like Adobe Illustrator, Inkscape, or Affinity Designer will make your life much easier when working with complex shapes in SVG. However, for simple shapes like this it doesn't hurt to understand the inner-workings of SVG curves. Not only will it help you malke mathematically perfect shapes but your code will also (usually) be much smaller than what an editor will produce.

The example I'm showing here is only one possible approach out of many to accomplishing this shape. I'll explain the procedure and series of commands briefly but I've also included a second copy of your shape with comments and additional shapes to highlight what the control points are doing (this helps me visualize SVG code).

First it moves to a point at x0, y 100 and draws a relative cubic curve (c) whose first control point is right 100px from the start point with no vertical change and whose second control point is right 180px and up 90px from the start point. The following s curve assumes that it will reflect the previous control point of the c curve before it so it only needs it's second control point and end point specified both of which are designated relative to the end point of the c curve and mirror the previous control points of the c curve. The rest is an absolute vertical line (V) to the bottom of the SVG, an absolute horizontal line to the bottom left corner (H) and a Z to close the path. SVG is awesome, hope this helps you.

1. You could create a multiple instances of refs to the Parent component itself according to the array and attach PanResponder to it

The problem seems to be in this line

setVisibility method doesn't take boolean param, which is returned by canScrollVertically. you have to set one of these params (ints)

visibility int: One of VISIBLE, INVISIBLE, or GONE. Value is VISIBLE, INVISIBLE, or GONE

so

If I have time tomorrow I will try to implement the following to your code but I can provide you with a working example of how to get mouse collision precision on a rotated rectangle. I had the same struggle with this and finally found a good explanation and code that I was able to get to work. Check out this website

Now for my own implementation I did not use the method on that website to get my vertices. As you'll see in my code I have a function called updateCorners() in my Square class. I also have objects called this.tl.x and this.tl.y (for each corner).

The formulas are what I use to get vertices of a translated and rotated rectangle and the corner objects are what are used to determine collision. From there I used the distance() function (Pythagorean theorem), the triangleArea() function, and then the clickHit() function which I renamed to collision() and changed some things.

Example in the snippet below

Using Provider you could wrap the widget that will need PageController with a ChangeNotifierProvider.value

Thanks to the comment from TrentonMcKinney I realized what the issue was:

In my case:

The values in each of my rows are the same, but each row is increasing.

But what I need for streamplot to work is:

Each row is the same, but the values in each row are increasing.

So I changed indexing = 'ij' to = 'xy':

This will move the circle to the mouse position. It doesn't move in one diagonal, but that can be changed.
