发送帖子请求时出现奇怪的错误。
// this map is passed to a function
final Map<String, dynamic> activityData = {
"userId": 1,
"name": activityName.text,
"description": activityDescription.text,
"startAt": activityStartAt.text,
"endsAt": activityEndAt.text,
"lat": _latitude,
"long": _longitude,
"category": 2,
"status": "pending"
};
// this code bellow is inside a async function
final http.Response response =
await http.post(Uri.encodeFull(url), body: activityData);
这是错误：
