【问题描述】：
我正在尝试将我的应用配置为显示测试广告，但是当我在 android 模拟器中运行该应用时，它崩溃并出现此错误：
/Users/me/.pub-cache/hosted/pub.dartlang.org/google_mobile_ads-0.13.2/lib/src/ad_containers.dart:454:9: Error: A value of type 'Type' can't be assigned to a variable of type 'DiagnosticsNode'.
- 'Type' is from 'dart:core'.
- 'DiagnosticsNode' is from 'package:flutter/src/foundation/diagnostics.dart' ('../../../flutter/packages/flutter/lib/src/foundation/diagnostics.dart').

从错误日志中我的理解是，>
A value of type 'Type' can't be assigned to a variable of type > 'DiagnosticsNode'在代码的某处出现了类型转换问题。它期望DiagnosticsNode类型的值，但提供Type类型。
