修改Android包名后Flutter应用异常：交互触发电脑崩溃

几周前开发了一款以Firebase为后端的Flutter应用，因原配置混乱想要修改Android包名。尝试用flutterfire configure重新配置Firebase新项目时出错，于是通过flutter create新建Flutter项目，复制旧项目的lib文件夹和pubspec.yaml文件替换新项目对应内容，再用flutterfire configure指定Android包名为com.mesak.done完成Firebase配置。

IDE未检测到代码错误，但首次启动Android模拟器时出现大量与包名修改相关的错误。虽然后来应用可成功构建并显示启动页，但一旦与模拟器或IDE交互，电脑就会崩溃。

Firebase配置详情 #

• 已启用邮箱密码认证
• 已启用Google认证
• 注册的Android应用包名为com.mesak.done（配置正确）
• Firebase Firestore和Storage配置无误

推测问题出在Android设置而非Firebase配置，以下是相关配置文件：

    def flutterSdkPath = {
        def properties = new Properties()
        file("local.properties").withInputStream { properties.load(it) }
        def flutterSdkPath = properties.getProperty("flutter.sdk")
        assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
        return flutterSdkPath
    }()
