GeoPath class Paths
A geographic path generator that takes a given GeoJSON geometry or feature object and generates SVG path data string or renders to a Canvas.
Paths can be used with projections or transforms, or they can be used to render planar geometry directly to Canvas or SVG.
Constructors
- GeoPath.new([GeoTransform? transform, Path? context])
- Creates a new geographic path generator with the default settings.
Properties
- context ↔ Path?
-
Context used to render the path.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- pointRadius ↔ double Function(Map?, [List? arguments])
-
A function which is computed per feature and used to display Point and
MultiPoint geometries with the radius being the returned number.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- transform ↔ GeoTransform?
-
A transform applied to any input geometry before it is rendered.

Methods
-
area(
Map object) → double -
Returns the projected planar area (typically in square pixels) for the
specified GeoJSON
object. -
bounds(
Map object) → List< List< num> > -
Returns the projected planar bounding box (typically in pixels) for the
specified GeoJSON
object. -
call(
[Map? object, List? arguments]) → String? -
Renders the given
object, which may be any GeoJSON feature or geometry object: -
centroid(
Map object) → List< double> -
Returns the projected planar centroid (typically in pixels) for the
specified GeoJSON
object. -
measure(
Map object) → double -
Returns the projected planar length (typically in pixels) for the
specified GeoJSON
object. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.
