Flutter Android构建失败：flutter_native_timezone命名空间缺失+AGP版本警告，尝试修复无效求助

各位大佬好！我最近在Android上运行Flutter应用时突然遭遇构建失败，核心问题和flutter_native_timezone包有关。我已经尝试了升级Kotlin版本、更换时区相关包、调整AGP版本等方法，但都没能解决问题，同时还收到了AGP版本即将被Flutter弃用的警告，实在没辙了来求助！

遇到的完整错误信息 #

首先是AGP版本的警告提示：

Warning: Flutter support for your project's Android Gradle Plugin version (Android Gradle Plugin version 8.1.0) will soon be dropped. Please upgrade your Android Gradle Plugin version to a version of at least Android Gradle Plugin version 8.3.0 soon. Alternatively, use the flag "--android-skip-build-dependency-validation" to bypass this check.
Potential fix: Your project's AGP version is typically defined in the plugins block of the settings.gradle file (/Users/rajpurohittanu/Documents/GitHub/generic-quiz-flutter/android/settings.gradle), by a plugin with the id of com.android.application. If you don't see a plugins block, your project was likely created with an older template version. In this case it is most likely defined in the top-level build.gradle file (/Users/rajpurohittanu/Documents/GitHub/generic-quiz-flutter/android/build.gradle) by the following line in the dependencies block of the buildscript: "classpath 'com.android.tools.build:gradle:'".

紧接着是导致构建失败的核心错误：

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':flutter_native_timezone'.

Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
Namespace not specified. Specify a namespace in the module's build file.

pubspec.yaml部分内容 #

name: generic_quiz_flutter
description: "A new Flutter project."
publish_to: 'none'

我已经尝试过的修复手段 #

• 将Kotlin版本升级到1.8.22
• 把AGP版本从8.1.0调整到8.2.2
• 尝试替换flutter_native_timezone为其他时区相关Flutter包
• 按照警告提示检查了AGP版本的配置位置，确认配置正确

有没有大佬遇到过类似的问题？或者有其他我没考虑到的修复方向？麻烦指点一下！
