達特：HttpException：解析失敗標頭值

HttpException：無法調用使用M2 release鏢http.Client.get（URI）的方法，當解析報頭值

http和oauth2庫。我正在嘗試使用該API來執行File: get。我成功將我的授權請求重定向到一個簡單的基於控制檯的http服務器以獲取令牌。然後下面的代碼導致異常：

oauth.Credentials credentials = new oauth.Credentials(code); 
http.Client client = new oauth.Client(CLIENT_ID, CLIENT_SECRET, credentials); 
Uri uri = new Uri("https://www.googleapis.com/drive/v2/files/$fileID"); 
Future<http.Response> result = client.get(uri);

下面是完整的堆棧跟蹤：
