我正在用Jetpack Compose开发一个Android应用程序，当我想用DrawImage（）添加新图像时，kotlin语言的编译给我一个错误，我从android的官方Jetpack Compose示例中获取代码开发人员页面添加图像。我已经花了几个小时寻找该问题的答案，但没有找到任何东西。有人可以帮我解决这个错误吗？

在我的应用程序级别build.gradle文件中，编译完成没有错误，但是当我运行该应用程序时，该图像未显示，然后该应用程序崩溃了。
这是我的 MainActivity.kt 文件：
composeOptions{
kotlinCompilerVersion "1.3.61-dev-withExperimentalGoogleExtensions-20200129"
kotlinCompilerExtensionVersion "0.1.0-dev04"
}
这是错误：

这是我的应用程序级别build.gradle：
