Puts one of the Maps SDK's own components on the map - a legend, a layer list, a search box, a basemap gallery. Each is a real web component that finds the map itself, so nothing has to be wired up.

Usage

add_widget(map, widget, position = NULL, expand = FALSE, ...)

remove_widget(map, widget = NULL)

Arguments

map

Defines which map or arc_map_proxy() to modify.

widget

default NULL. Defines which widget to take off, by the name it was added with. NULL removes every widget.

position

default NULL. Defines which corner it sits in, one of "top-left", "top-right", "bottom-left", "bottom-right", or the direction-aware "top-start", "top-end", "bottom-start", "bottom-end". Each widget has its own default.

expand

default FALSE. Defines whether the widget is collapsed behind a button rather than drawn open. Worth it for the panels - the legend, layer list, basemap gallery - which otherwise cover the map. Collapsed widgets sharing a corner close each other when opened.

...

Named properties of the component itself, written either snake_case or camelCase. map_widgets() lists what each one takes.

Value

map, with the widget added.

Details

Adding a widget that is already on the map replaces it, which is what makes add_widget() idempotent across arc_update() flushes. remove_widget() takes one off again.
