I am trying to migrate code from ArcGis Javascript 3x to 4x. I have noticed "esri/toolbars/navigation"  is not on ArcGis Javascript 4x.  I want recreate the navigation toolbars on ArcGis Javascript 4x, simliar to the one on this link ArcGIS API for JavaScript Sandbox (from ArcGis Javascript 3x)

My question is where can I locate a class similar to it on ArcGis Javascript 4x.

Bobo,

 

   The 4.x API does NOT have a navigation toolbar like the 3.x API does yet. So I created this app that replicates the 3.x navigation toolbar.
