power_geojson library
Classes
- FeatureCollectionProperties
- Represents a set of properties for customizing the appearance of GeoJSON feature collections.
- Flow
- A class to represent Flow events.
- MarkerProperties
- Represents properties for a marker on a map.
- NativeRuntime
- Functionality available on the native runtime.
- PolygonProperties
- A class representing properties for rendering polygons on a map.
- PolylineProperties
- PowerEsriJSON
- PowerEsriJsonTransform
- PowerEsriJsonTransformer
- PowerGeoFeature
- Represents a feature in GeoJSON data, which can include geometry and associated properties.
- PowerGeoJSONClipper
- PowerGeoJSONFeatureCollection
- Represents a collection of PowerGeoFeatures that can include points, linestrings, and polygons.
- PowerGeoJSONFeatureCollections
- A utility class for fetching and displaying GeoJSON feature collections as widgets.
- PowerGeoJSONMarkers
- A utility class for fetching and rendering markers from various sources.
- PowerGeoJSONPolygons
- A utility class for loading and displaying polygons on a map from various sources.
- PowerGeoJSONPolylines
- PowerGeoLineString
- Represents a line string geometry within a geographic feature.
- PowerGeoPoint
- Represents a point geometry within a geographic feature.
- PowerGeoPolygon
- Represents a polygon geometry within a geographic feature.
- PowerJSON
- Service
- Access information about the service protocol and control the web server that provides access to the services provided by the Dart VM for debugging and inspecting Dart programs.
- ServiceExtensionResponse
- A response to a service protocol extension RPC.
- ServiceProtocolInfo
- Service protocol is the protocol that a client like the Observatory could use to access the services provided by the Dart VM for debugging and inspecting Dart programs. This class encapsulates the version number and Uri for accessing this service.
- Timeline
- Add to the timeline.
- TimelineTask
- An asynchronous task on the timeline. An asynchronous task can have many (nested) synchronous operations. Synchronous operations can live longer than the current isolate event. To pass a TimelineTask to another isolate, you must first call pass to get the task id and then construct a new TimelineTask in the other isolate.
- UserTag
- A UserTag can be used to group samples in the DevTools CPU profiler.
Enums
- LayerMarkerIndexes
- An enumeration representing indexes for marker layer properties.
- LayerPolygonIndexes
- Enum defining indexes for polygon layer properties.
- LayerPolylineIndexes
Extensions
- HexColor on Color
-
LantLngX
on List<
List< double> > - An extension on lists of lists containing double values to provide a convenient method for converting them into a list of LatLng objects.
-
ListABC
on List<
T> -
ListListLatLngX
on List<
List< List< >double> > -
MarkerXX
on List<
double> -
PointXList
on List<
double> -
PolygonsXX
on List<
List< List< >double> > -
PolylineXX
on List<
List< double> > - PolyX on Polygon
- StringX on String
- XListPoint on LatLng
Properties
- extensionStreamHasListener → bool
-
Whether the "Extension" stream currently has at least one listener.

Current reachability barrier state.
no setter
Functions
-
checkEsri(
String readasstring) → String -
debugger(
{bool when = true, String? message}) → bool -
If
whenis true, stop the program as if a breakpoint were hit at the following statement. -
getCurrentTag(
) → UserTag - Returns the current UserTag for the isolate.
-
getDocumentsDir(
) → Future< Directory> -
getExternalDir(
) → Future< List< Directory> ?> -
inspect(
Object? object) → Object? -
Send a reference to
objectto any attached debuggers. -
log(
String message, {DateTime? time, int? sequenceNumber, int level = 0, String name = '', Zone? zone, Object? error, StackTrace? stackTrace}) → void - Emit a log event.
-
postEvent(
String eventKind, Map eventData, {String stream = 'Extension'}) → void -
Post an event of
eventKindwith payload ofeventDatato the "Extension" event stream. -
registerExtension(
String method, ServiceExtensionHandler handler) → void -
Register a ServiceExtensionHandler that will be invoked in this isolate
for
method. NOTE: Service protocol extensions must be registered in each isolate. -
zoomTo(
List< List< features, MapController? mapController) → voiddouble> ?> - Zooms the map view to fit the specified geographic features.
Typedefs
-
ServiceExtensionHandler
= Future<
ServiceExtensionResponse> Function(String method, Map<String, String> parameters) - A service protocol extension handler. Registered with registerExtension.
- TimelineAsyncFunction = Future Function()
-
TimelineSyncFunction<
T> = T Function() - A typedef for the function argument to Timeline.timeSync.
