Flutter集成Firebase遇build.gradle报错：找不到谷歌服务插件

报错详情 #

FAILURE: Build failed with an exception.

• 报错位置：构建文件C:\Users\82102\Documents\Folder\Coding\Flutter\kyunggi_life\android\app\build.gradle第4行
• 问题原因：未找到插件id: 'com.google.gms.google-services'，该插件不在Gradle核心插件中，且插件仓库中未指定版本号

官方建议：

• 使用--stacktrace选项获取堆栈跟踪
• 使用--info或--debug选项获取更多日志
• 使用--scan选项获取完整分析

构建1秒后失败，执行Gradle任务assembleDebug耗时2064ms，最终错误提示：Gradle任务assembleDebug以退出码1失败

已尝试的排查操作 #

• 耗时约3小时查找解决方案，因理解不足无法应用现有方案
• 推测问题出在app/build.gradle和android/build.gradle两个配置文件中
• 已执行的修复尝试：
  1. 在app/build.gradle中添加ndkVersion "26.1.10909125"、apply plugin: 'com.google.gms.google-services'及任务执行顺序代码
  2. 检查android/build.gradle中的buildscript配置，确认已添加google()、mavenCentral()仓库及com.google.gms:google-services:4.3.10的classpath依赖
