Flutter 报错 Expected a value of type 'List<String>', but got one of type 'List<dynamic>'

Flutter 报错 Expected a value of type 'List<String>', but got one of type 'List<dynamic>'

服务端返回的数据是List<dynamic> callback给业务的时候想返回一个List<String>类型的

解决方法如下

        var hotwords = (response["hotwords"] as List)
            ?.map((item) => item as String)
            ?.toList();

需要的老铁可以拿去用
