Usage

To use the google_maps_routes package, first depend on it.

Then import it where you want to use it

import 'package:google_maps_routes/google_maps_routes.dart';

To use it you need a List of points like this:

/// LatLng is included in google_maps_flutter
List<LatLng> points = [
    LatLng(latitude, longitude),
    LatLng(latitude, longitude),
    LatLng(latitude, longitude),
    LatLng(latitude, longitude),
];

Then you need to instantiate this plugin

MapsRoutes route = new MapsRoutes();

To create a route, just call the following function:

/// routeName is a string and can be anything; it can include spaces but
/// they will be replaced with a dash
/// example: 'Example route'

/// color is a Color type and will be used as the polyline color:
/// example: Color.fromRGBO(130, 78, 210, 1.0)

/// googleApyKey is a string and is a google directions API key
/// example: get it at
/// https://developers.google.com/maps/documentation/directions/get-api-key
await route.drawRoute(points, routeName, color, googleApiKey);

To use a different travel mode, use the travelMode parameter.

/// Options: driving, bicycling, transit, walking
await route.drawRoute(
    points,
    routeName,
    color,
    googleApiKey,
    travelMode: TravelModes.walking
);

To display the polylines you need to add a polylines parameter to your google map widget.

GoogleMap(
    polylines: route.routes
)

If you ever want to clear the routes, just call:

route.routes.clear();
