This is the simplest way to set up a [draggable] modifier. When constructing this

Default implementation of `DraggableState` interface that allows to pass a simple action that
will be invoked when the drag occurs.

This is the simplest way to set up a `draggable` modifier. When constructing this
`DraggableState`, you must provide a `onDelta` lambda, which will be invoked whenever drag
happens (by gesture input or a custom `DraggableState.drag` call) with the delta in pixels.

If you are creating `DraggableState` in composition, consider using `rememberDraggableState`.

#### Parameters

| --- | --- |
| onDelta | callback invoked when drag occurs. The callback receives the delta in pixels. |
