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.
final
to MapLatLng
