如何在Flutter中使用YouTubeAPI

类型：“渠道”

仅对于视频，请指定>类型：“视频”

仅对播放列表指定>类型：“播放列表”

maxResults（int）可以是1-50'

var dateTimeString = "20181230183000000";
DateTimeOffset dto;
if (DateTimeOffset.TryParseExact(dateTimeString,"yyyyMMddHHmmssfff",CultureInfo.invariantculture,DateTimeStyles.AssumeUniversal |
DateTimeStyles.AdjustToUniversal,out dto))
{
Console.WriteLine(dto);
}


此代码获取json数据以存储在ytResult中：

int max = 25;
String type = "channel";
YoutubeAPI ytApi = new YoutubeAPI(key,maxResults: max,Type: type);


这是我的全部代码，但未得到任何响应

这是我的颤动代码，用于按关键字列出视频
