routePlanningDraw static method

void routePlanningDraw({ required List<PlanItem> itemList, String? lineImgPath, Color? lineColor, String? pathlineId, required AMapUIController uiController, required AMapController mapController, OnComplete? onComplete, })

线路规划 一键绘制 不建议使用一键绘制，最好使用线路规划接口获取点位后参考下面自己绘制
