android - Kotlin Multiplatform 中共享抛出 NoSuchMethodError 的实际/预期乐趣
问题描述
我正在 Kotlin Multiplatform 的帮助下开发一个虚拟天气应用程序。我正在使用 Decompose 和 MVIKotlin 来尝试共享除本机 uis、IOS 的 SwiftUI 以及桌面和 Android 的 Compose 之外的所有业务逻辑。
我正在尝试期望可组合（用于深色主题和加载图像）
// In common main
@Composable
expect fun isDarkMode() : Boolean
@Composable
expect fun loadWeatherIcon(id : Int) : Painter
// In android main
@Composable
actual fun isDarkMode() : Boolean {
return androidx.compose.foundation.isSystemInDarkTheme()
}
@Composable
actual fun loadWeatherIcon(id : Int) : Painter {
return painterResource(id)
}
//In Desktop main
@Composable
actual fun isDarkMode() : Boolean {
return false //isSystemInDarkTheme()
}
@Composable
actual fun loadWeatherIcon(id : Int) : Painter {
return loadWeatherIcon(id)
}
这意味着它们都已实现，但由于某种原因，NoSuchMethodError 发生了崩溃。我发现了一些类似的问题，但它们都有暂停乐趣和默认参数。同时我的方法应该像jetpack todo compose sample一样工作，这是我的项目（如果你想测试发生了什么，你可以克隆它并运行它，它应该会立即崩溃）

解决方案
我遇到了一个类似的问题，@Composable在运行时在不同的 Gradle 模块中看不到带注释的预期函数。因此java.lang.NoSuchMethodError例外。解决方案是使预期的函数成为内部函数，并将公共包装函数委托给该内部函数。
崩溃：
@Composable
expect fun Image() { ... }
不崩溃：
@Composable
internal expect fun InternalImage() { ... }
@Composable
fun Image() {
InternalImage()
}
