我正在开发一个较旧的 Flutter 应用程序，由于 API 级别过时，该应用程序已从 Play 商店中删除。我目前正在尝试更新并重新发布它，但在更新过程中遇到了这些问题。 我需要按照 Play 商店的要求将 Android 最低 API 级别维持在 33。
我在尝试在 Flutter 中编译 APK 时遇到问题。该错误发生在

此外，我收到了一些关于 tflite 插件中已弃用 API 的警告，我四处寻找解决方案，但无法在修复方面取得很大进展。

我尝试清理项目并重建 APK，检查依赖项版本，并检查 build.gradle 文件以确保一切设置正确。我还更新了依赖项并确保 Kotlin 版本和 Gradle 插件兼容。
我还注意到 14 个软件包具有与当前依赖关系约束不兼容的较新版本。

由于我仍在学习如何使用 Flutter 和 Gradle，所以我不确定如何解决这个问题。任何有关如何解决此问题并成功编译 APK 的指导或建议将不胜感激。谢谢！
在 android/build.gradle 上添加此解决方法已经为我们解决了这个问题。
