MapProps

MapProps = object

Props for the <Map> model component — mirror the configurable properties of the native ArcGISMap. Reconciled into the underlying SharedObject via applyProps.

Properties

basemap?

optional basemap?: BasemapStyle

Defined in: src/ExpoArcgis.types.ts:45

Basemap style. Defaults to arcGISTopographic. Ignored when portalItem is set.

basemapLanguage?

optional basemapLanguage?: string

Defined in: src/ExpoArcgis.types.ts:53

Language for basemap place-name labels. Only applies when basemap is a built-in style string. Special values: "global" — English worldwide; "local" — local place names; "default" — SDK default; "applicationLocale" — device locale. Any other value is treated as a BCP-47 language tag (e.g. "fr", "ar", "zh-Hans"). Corresponds to BasemapStyleParameters.language on both platforms.

basemapWorldview?

optional basemapWorldview?: string

Defined in: src/ExpoArcgis.types.ts:59

Worldview code for disputed-boundary rendering. Only applies when basemap is a built-in style. Known codes: "CN", "IN", "IL", "JP", "MA", "PK", "KR", "AE", "US", "VN". Corresponds to BasemapStyleParameters.worldview on both platforms.

bookmarks?

optional bookmarks?: object[]

Defined in: src/ExpoArcgis.types.ts:87

Named saved viewpoints stored on the map. Replaces the map’s bookmark list each time the prop changes. Each entry creates a native Bookmark(name, Viewpoint(latitude, longitude, scale)). Navigation to a bookmark is done separately via the <MapView viewpoint> prop.

name

name: string

viewpoint

viewpoint: object

viewpoint.latitude

latitude: number

viewpoint.longitude

longitude: number

viewpoint.scale

scale: number

initialViewpoint?

optional initialViewpoint?: Viewpoint

Defined in: src/ExpoArcgis.types.ts:73

Center + scale applied when the map first loads.

maxExtent?

optional maxExtent?: Geometry

Defined in: src/ExpoArcgis.types.ts:71

Constrains panning to this envelope — the user cannot scroll the map outside this extent. Must be an envelope geometry. Omit (or pass undefined) to remove the constraint. Maps to maxExtent on both platforms.

mobileMapPackagePath?

optional mobileMapPackagePath?: string

Defined in: src/ExpoArcgis.types.ts:81

Display an offline map from a mobile map package (.mmpk) at this local path — e.g. the directory returned by offline.generateOfflineMap. The package loads asynchronously and the map appears once ready.

portalItem?

optional portalItem?: PortalItem

Defined in: src/ExpoArcgis.types.ts:75

Load the map from an ArcGIS web map. Construction-only (set once; remount to change).

referenceScale?

optional referenceScale?: number

Defined in: src/ExpoArcgis.types.ts:65

The scale at which feature symbols and text are drawn at their authored size. Features scale relative to this value as the user zooms in and out. Set to 0 (or omit) to disable reference scaling. Maps to referenceScale on both platforms.
