谷歌地图调用代码 #

Stack(
  children: [
    Container(
      height: 500,
      width: 380,
      color: Colors.red,
      child: GoogleMap(
        polylines: _polylines,
        myLocationButtonEnabled: true,
        zoomControlsEnabled: true,
        initialCameraPosition: _initialCameraPosition,
        markers: _markers,
        onMapCreated: (GoogleMapController controller) {
          _googleMapController = controller;
        },
      ),
    )
  ]
),

Polyline绘制逻辑代码 #

PolylineResult result = await polylinePoints.getRouteBetweenCoordinates(
  googleAPIKey,
  PointLatLng(44.85552543453359,-0.5484378447808893),
  PointLatLng(listlatitudeLocation[0],  listlongitudeLocation[0])
  // PointLatLng(44.86301953775456, -0.550416465058058)
);
print('Result Status  ${result.status}');
if (result.status == 'OK') {
  result.points.forEach((PointLatLng point) {
    polylineCoordinates.add(LatLng(
      point.latitude,
      point.longitude
    ));
  });
  _polylines.add(Polyline(
    polylineId: PolylineId('Polyline_Etape_1'),
    width: 5,
    color: Colors.blue,
    points:polylineCoordinates,
  ));
}
