当我在 flutter run 中运行代码时，会发生错误。最近我更改了 gradle 属性文件。 7版本到8版本。

如何解决这个问题。

尝试在 flutter 中修复此问题。此应用程序在 ios 中成功运行，错误仅发生在 android 中。

什么错误。为什么会发生

android flutter macos gradle build.gradle

此依赖项中的问题

实现“androidx.core:core-ktx:+”

只需添加最新的 kotlin 版本而不是“+”并同步，同步后即可 重建gradle问题就解决了。

解决方案： 从 实现“androidx.core:core-ktx:+” 到： 实现“androidx.core:core-ktx:1.13.1”更新依赖关系。
