searchAround static method

Future<List<AMapPoi>> searchAround(LatLng center, { String keyword = '', String city = '', String types = '', int pageSize = 20, int page = 1, int radius = 1500, })

周边搜索poi

center 中心点

keyword 查询关键字，多个关键字用“|”分割

radius 查询半径，范围：0-50000，单位：米 default = 1500

types 类型，多个类型用“|”分割 可选值:文本分类、分类代码

city 城市名称

pageSize 每页记录数, 范围1-25, default = 20

page 当前页数, 范围1-100, default = 1

Implementation

  assert(pageSize >= 1 && pageSize <= 25, 'pageSize must be between 1 and 25');
  assert(radius >= 0 && radius <= 50000, 'radius must be between 0 and 50000');
  final List? dataList = await _channel.invokeMethod('searchAround', {
    'keyword': keyword,
    'city': city,
    'types': types,
