Constructors

MapLine({required MapLatLng from, required MapLatLng to, List<double>? dashArray, Color? color, double? width, StrokeCap? strokeCap, VoidCallback? onTap})
Creates a MapLine.
const

Properties

color → Color?
Color of the line.
final
dashArray → List<double>?
Apply dash pattern for the line.
final
from → MapLatLng
The starting coordinate of the line.
final
hashCode → int
The hash code for this object.
no setterinherited
onTap → VoidCallback?
Callback to receive tap event for this line.
final
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
strokeCap → StrokeCap?
Applies stroke cap to the start and end of the line. You can set StrokeCap.round to get a semi-circle or StrokeCap.square to get a semi-square at the edges of the line.

inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
