GeoPolylineWidget class

A polyline widget for displaying paths and routes on maps.

This widget represents a connected series of line segments with customizable appearance including color, width, cap style, and dash patterns.

Example:

final route = GeoPolylineWidget(
  points: [
    GeoPoint(latitude: 37.7749, longitude: -122.4194),
    GeoPoint(latitude: 37.7849, longitude: -122.4094),
    GeoPoint(latitude: 37.7949, longitude: -122.3994),
  ],
);

// Using route preset
final path = GeoPolylineWidget.route(points: myPoints);
