Constructors

VectorSource({required String id, String? url, List<String?>? tiles, List<double?>? bounds, Scheme? scheme, double? minzoom, double? maxzoom, String? attribution, bool? volatile, double? prefetchZoomDelta, TileCacheBudget? tileCacheBudget, double? minimumTileUpdateInterval, double? maxOverscaleFactorForParentTiles, double? tileRequestsDelay, double? tileNetworkRequestsDelay})

Properties

attribution → Future<String?>
Contains an attribution to be displayed when the map is shown to a user.
no setter
bounds → Future<List<double?>?>
An array containing the longitude and latitude of the southwest and northeast corners of the source's bounding box in the following order: [sw.lng, sw.lat, ne.lng, ne.lat]. When this property is included in a source, no tiles outside of the given bounds are requested by Mapbox GL.
no setter
hashCode → int
The hash code for this object.
no setterinherited
id ↔ String
The ID of the Source.
getter/setter pairinherited
maxOverscaleFactorForParentTiles → Future<double?>
When a set of tiles for a current zoom level is being rendered and some of the ideal tiles that cover the screen are not yet loaded, parent tile could be used instead. This might introduce unwanted rendering side-effects, especially for raster tiles that are overscaled multiple times. This property sets the maximum limit for how much a parent tile can be overscaled.
no setter
maxzoom → Future<double?>
Maximum zoom level for which tiles are available, as in the TileJSON spec. Data from tiles at the maxzoom are used when displaying the map at higher zoom levels.
no setter
minimumTileUpdateInterval → Future<double?>
Minimum tile update interval in seconds, which is used to throttle the tile update network requests. If the given source supports loading tiles from a server, sets the minimum tile update interval. Update network requests that are more frequent than the minimum tile update interval are suppressed.
no setter
minzoom → Future<double?>
Minimum zoom level for which tiles are available, as in the TileJSON spec.
no setter
prefetchZoomDelta → Future<double?>
When loading a map, if PrefetchZoomDelta is set to any number greater than 0, the map will first request a tile at zoom level lower than zoom - delta, but so that the zoom level is multiple of delta, in an attempt to display a full map at lower resolution as quick as possible. It will get clamped at the tile source minimum zoom. The default delta is 4.
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
scheme → Future<Scheme?>
Influences the y direction of the tile coordinates. The global-mercator (aka Spherical Mercator) profile is assumed.
no setter
tileCacheBudget → Future<TileCacheBudget?>
This property defines a source-specific resource budget, either in tile units or in megabytes. Whenever the tile cache goes over the defined limit, the least recently used tile will be evicted from the in-memory cache. Note that the current implementation does not take into account resources allocated by the visible tiles.
no setter
tileNetworkRequestsDelay → Future<double?>
For the tiled sources, this property sets the tile network requests delay. The given delay comes in action only during an ongoing animation or gestures. It helps to avoid loading the transient tiles from the network and thus to avoid redundant network requests. Note that tile-network-requests-delay value is superseded with tile-requests-delay property value, if both are provided.
no setter
tileRequestsDelay → Future<double?>
For the tiled sources, this property sets the tile requests delay. The given delay comes in action only during an ongoing animation or gestures. It helps to avoid loading, parsing and rendering of the transient tiles and thus to improve the rendering performance, especially on low-end devices.
no setter
tiles → Future<List<String?>?>
An array of one or more tile source URLs, as in the TileJSON spec.
no setter
url → Future<String?>
A URL to a TileJSON resource. Supported protocols are http:, https:, and mapbox://<Tileset ID>.
no setter
volatile → Future<bool?>
A setting to determine whether a source's tiles are cached locally.
no setter
