Properties

code → String

Code of this CRS.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

infinite → bool

If true, the coordinate space will be unbounded (infinite in both axes).

no setter, inherited

latBounds → Tuple2<double, double>

Bounds for latitude

no setter, inherited

lngBounds → Tuple2<double, double>

Bounds for longitude

no setter, inherited

projection → Projection

Projection value of this CRS.

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

transformation → Transformation

Transformation object of this CRS.

no setter, override

Methods

distance(LatLng position, LatLng destination) → double

Calculate distance from position to destination.

inherited

getProjectedBounds(double? zoom) → Bounds?

Returns the projection's bounds scaled and transformed for the provided zoom.

inherited

latlngToPoint(LatLng? position, double? zoom) → UPoint

Projects latlng coordinates into pixel coordinates for a given zoom.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

pointToLatLng(UPoint point, double? zoom) → LatLng?

The inverse of latlngToPoint. Projects pixel coordinates on a given zoom into latlng coordinates.

inherited

project(LatLng? latlng) → UPoint?

Projects geographical coordinates into coordinates in units accepted for this CRS (e.g. meters for EPSG:3857, for passing it to WMS services).

inherited

scale(double? zoom) → double?

Returns the scale used when transforming projected coordinates into pixel coordinates for a particular zoom.

inherited

toString() → String

A string representation of this object.

inherited

unproject(UPoint point) → LatLng?

Given a projected coordinate returns the corresponding LatLng. The inverse of project.

inherited

wrapLatLng(LatLng latlng) → LatLng

Returns a LatLng where lat and lng has been wrapped according to the CRS's wrapLat and wrapLng properties, if they are outside the CRS's bounds.

inherited

wrapLatLngBounds(LatLngBounds bounds) → LatLngBounds

Returns a LatLngBounds with the same size as the given one, ensuring that its center is within the CRS's bounds.

inherited

zoom(double scale) → double

Inverse of scale(), returns the zoom level corresponding to a scale factor of scale.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
