FastViewTree

FastViewTree is a Kotlin written android lib which provides the ability to fetch the view tree information during runtime.

FastViewTree gives you another option during debugging some complex UI issue.

FastViewTree comes with not only view tree info but also size and visibility info of the view.

The coordinates info of view is not yet included but is in the plan.
