ReorderableDraggable class
Enables drag and drop behaviour for child.
Important methods: onCreated
and onBuilding
.
onCreated
is called after widget was built to return _globalKey
for calculating position and size.
onBuilding
is always called if isBuilding
of reorderableEntity is true.
That means, that there was an update in the position, usually a new position.
