Line's heigh is not stable with 3x Android devices

[leoliupei]

Just open the official demo in GooglePlay. You can simply find that thin line's heigh is not stable with 3x Android devices. At different places, a 1dp line's heigh range from 0px to 3px. I faced the same bug in ReactNative, seems to be a bug in Yoga.

I hope Flutter can solve is problem!!!

This looks like a known problem with antialiasing and mapping from logical pixels to device pixels. There's an open issue for a documentation fix: #14288
