Get access to the direction of the swipe when a swipe event occurs.

I’m thinking, adding support for left and right swiping is no problem, but what about up and down? If you want to attach special behavior to that, should the screen still scroll up and down if you swipe up and down?

Or is it really left vs. right swiping you’re interested in here?

up and down is mostly used for lists so if we could get left and right we could do things like changing to one screen with left swipe and another with right swipe.

From 0.4.3 onwards, the implicit Callback event argument will have a direction attribute that can be either ‘right’ or ‘left’:

group {
  item(onswipe={ log(event.direction); }) {
    "Swipe me!"
  }
}
