Enhancement(web): Support onDrag/detectDragGestures Modifier on Web Platform #4493

Closed whitescent closed 1 week ago

whitescent commented 6 months ago

It seems that onDrag/pointerInput detectDragGestures doesn't work with Web Platform, here's a simple example

var offset by remember { mutableStateOf(Offset.Zero) }
Image(
  painter = painterResource(Res.drawable.logo),
  contentDescription = null,
  modifier = Modifier.offset {
    IntOffset(offset.x.toInt(), offset.y.toInt())
  }
    .size(48.dp)
    .pointerInput(Unit) {
      detectDragGestures(
        matcher = PointerMatcher.Primary
      ) {
        offset += it
      }
    }
)

Thanks for reporting! It's rather a bug, since it's available for using it in the code but it doesn't work as expected :) The feature was not implemented internally yet.
