[featurePR]: flutter_boost 适配 flutter 3.32

我在使用 flutter 3.32.5 版本的 flutter module 进行现有 Android 原生应用集成时出现异常, 翻阅issues后发现与 https://github.com/alibaba/flutter_boost/issues/2197#issue-3002062807 问题相同, 经过 https://github.com/alibaba/flutter_boost/issues/2185#issuecomment-2693455645 方法修改后编译正常, 其中https://github.com/alibaba/flutter_boost/issues/2185#issuecomment-2816670461 写道MethodChannel异常, 我使用 [battery_plus](https://pub.dev/packages/battery_plus) 插件测试MethodChannel后正常, 因项目需要使用flutter_boost, 故提交此Issues希望提交Pull requests修复此问题, 望官方批准.

Start by reproducing the reported exception while integrating a Flutter 3.32.5 module into an Android native app, then read linked issues 2197 and 2185, including the referenced MethodChannel discussion. Compare the behavior with the stated workaround and the battery_plus MethodChannel test; done means the integration builds and the affected MethodChannel behavior works without that workaround.
