Is there an existing issue for this?

• I have searched the existing issues
• I have read the guide to filing a bug

Steps to reproduce

1. Copy and paste this code fromDartPad into a flutter applications main.dart file
2. Fire up an iOS Simulator utilizing an IPAD 12.9 inch
3. Draw a straight line from right to left then go back to right
4. You will see that the end line (on the left) does not cap and is instead a sharp rectangle.

Expected results

I would expect the line to have a rounded cap when going from right to left as it does on Android simulator, and web. This only occurs on IOS devices

Actual results

The end of the line when going right to left and back to left does not cap the end of the line on the left.
