Aspect ratio

Aspect ratio is the ratio between a node’s width and height: a node with an aspect ratio of 2 is twice as wide as it is tall.

• Accepts any number greater than 0. The default is unset.
• Respects the node’s min and max dimensions.
• Has higher priority than flex grow.
• If aspect ratio, width and height are all set, the cross-axis dimension is overridden.

node.setAspectRatio(16 / 9);
