骑行路线规划可以根据起终点获取骑行路线规划数据，并可以通过添加Polyline绘制出骑行路线。

效果图如下：

let option: BikingRoutePlanOption = {
  from: PlanNode.withLocation(fromArr),
  to: PlanNode.withLocation(toArr)
}
RoutePlanSearch.newInstance().bikingSearch(option)
  .then((res: BikingRouteResult) => {
    let resultLine: Array<LatLng> = []
    if (typeof res.routeLines != 'undefined') {
      let steps = res.routeLines[0].steps
      for (let i = 0; i < steps.length; i++) {
        let line: Array<LatLng> = [];
        line = parseStrPathToLLArray(steps[i].pathString);
        resultLine = resultLine.concat(line)
      }
    }
    let polyline: Polyline = new Polyline({
      points: resultLine,
      fillcolor: '#6af',
      width: 10,
      join: SysEnum.LineJoinType.ROUND,
      cap: SysEnum.LineCapType.ROUND,
      isThined: true,
      isGeodesic: true
    });
    this.mapController?.addOverlay(polyline);
  }).catch((err: Error) => {
      // TODO
})
