我的 flutter 项目的外部库出现错误。当我将我的项目作为调试版本运行时，一切正常，但是当我将我的项目作为发布版本运行时，我会遇到如下问题。我尝试更改compileSdk版本，但没有帮助。我尝试更改 buildType，但仍然不起作用。问题出在 2 个库上：
android_package_manager: ^0.6.0
flutter_logs: ^2.1.11
应用程序等级：
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '7'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')

flutterVersionName = '2.7.0'

* What went wrong:
A problem occurred configuring project ':android_package_manager'.
> 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. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.
If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file.

这是您使用的
android_package_managernamespace或者，您可以降级到 AGP v7 和 Gradle v7，但我不建议这样做，除非是短暂的（如果您处于紧急情况）。
