Camera State

Additional Developer Resources

Every time any camera property is changing UX Framework produces its new state. You may collect such information via Dash.controller.observeCameraState() flow.

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    
        lifecycleScope.launch {
            repeatOnLifecycle(Lifecycle.State.STARTED) {
                Dash.controller
                    .observeCameraState()
                    .debounce(1000.milliseconds)
                    .collect(this) { cameraState ->
                        // do something with camera state
                    }
                
                
                
                Dash.controller.observeRoutes()
                    .collect { /* RouteChangeEvent */ event ->
                        val activeNavRoute = event.routes.firstOrNull()
                        // Do something with active NavigationRoute
                    }
            }
        }
    }
}

Be aware that camera state properties change often. It might be good to limit received calls with debounce() operator.
