searchAround method

Future<SearchPoiResponse> searchAround(LatLng location, { String? keywords, String? types, int? radius, String? sortRule, String? region, bool? cityLimit, String? showFields, int? pageSize, int? pageNum, String? output, })

周边搜索 location: 必填，中心点坐标 keywords: 地点关键字 types: 指定地点类型 radius: 搜索半径,取值范围:0-50000，大于50000时按默认值，单位：米,默认为5000 sortrule: 排序规则，按距离排序：distance；综合排序：weight，默认为distance region: 搜索区划 city_limit: 指定城市数据召回限制，可选值：true/false，默认为false show_fields: 返回结果控制 page_size: 当前分页展示的数据条数，page_size的取值1-25，默认为10 page_num: 请求第几分页，page_num的取值1-100，默认为1 output: 返回结果格式类型，默认格式为json，目前只支持json格式
