Point class Null safety
A Point is a single position in a coordinate system, with properties. A Point can be created from a Coordinate, from a WKT String, or from a GeoJSON Map. A Point can be converted to a WKT String or GeoJSON Map.
Example:
Point(Coordinate(1, 2), {'name': 'point'}); // Point(Coordinate(1, 2), {'name': 'point'})
Point(Coordinate(1, 2), {'name': 'point'}).toWKT(); // POINT(1 2)
Point(Coordinate(1, 2), {'name': 'point'}).toJson(); // {'type': 'Feature', 'geometry': {'type': 'Point', 'coordinates': [1, 2]}, 'properties': {'name': 'point'}}

Methods
-
explode(
) → List< Point> -
Explodes the
Point
into a list ofPoint
s Pretty useless, but needs to overwrite the Feature method.override -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a non-existent method or property is accessed.
inherited
-
toJson(
) → Map< String, dynamic> -
Converts the Point to a GeoJSON Map.
override
-
toString(
) → String -
A string representation of this object.
override
-
toWKT(
) → String -
Converts the Point to a WKT String.
override
Operators
-
operator ==(
Object other) → bool -
Checks for equality between two Points, specifically if they have the same coordinate and properties.
