问题描述
我有这个错误； 会不会是token有问题，上面写着Uri无效的token，但是我之前登录过，为什么读不出来？标题我像这样添加令牌..但它不起作用如何解决它？我可能做错了什么？
所以地图，如果哪里，哪里或其他东西不起作用.. 我是这个平台的新手，我可能问了一些非常简单的问题，抱歉。 谢谢大家....

解决方法
我认为问题出在这里
response.toList().where((e){
print("PEOPLE COUNT= ${ e.gamePlayed}");
});
原因如错误消息所述。响应变量为空，您试图将空转换为列表，而 Dart 不喜欢那样。实现一些方法来处理响应为空的场景，例如在那里有一个 if 语句，这有望解决您的问题
