ViewportPluginImpl

class ViewportPluginImpl(handler: Handler) : ViewportPlugin

Mapbox default implementation for ViewportPlugin.

The Viewport plugin allows to track objects on a map.

It provides a structured approach to organizing camera management logic into states and transitions between them.

at any given time, the viewport is either:

  • idle (not updating the camera)

  • in a state (camera is being managed by a ViewportState)

  • transitioning (camera is being managed by a ViewportTransition)
