Flutter升级后，我无法构建应用程序。

../../../flutter/.pub-cache/hosted/pub.dartlang.org/nfc_in_flutter-2.0.5/lib/src/api.dart:524:54: Error: The operator '[]' isn't defined for the class 'Object'.
 - 'Object' is from 'dart:core'.
Try correcting the operator to an existing operator, or defining a '[]' operator.
          throw NFCTagSizeTooSmallException(e.details["maxSize"] ?? 0);
                                                     ^
