Landroidx/compose/foundation/layout/BoxScope$Companion；类型的java.lang.NoSuchFieldError:无字段陪伴

Question

我第一次使用，但是我得到了这个错误。我还没有弄清楚问题到底在哪里，但我使用的是单活动体系结构。如果需要更多的信息，请通知我。根据错误，问题似乎来自于脚手架。

                val scaffoldState = rememberScaffoldState()

                Scaffold(
                    scaffoldState = scaffoldState,
                    snackbarHost = {
                        SnackbarHost(hostState = it)
                    }
                ) {

Answer 1

这个答案是基于CommonsWare的评论，它帮助我修正了错误。

解决方案是使用一组一致的组合依赖项。beta04在合成基础工件中对BoxScope进行了更改。也许你得到了那个工件的beta04，但是得到了一个较旧的合成材料工件。

Answer 2

我也犯了同样的错误，并通过更新撰写版本来解决它。由Android生成的新项目模板附带了复合版本1.0.0-beta01

打开build.gradle文件并更新

compose_version = '1.0.0-beta05'

或者更新，如果你愿意的话。

Answer 3

在将androidx.navigation:navigation-compose:1.0.0-alpha10作为依赖项添加之后，我得到了这个错误。

对我起作用的是降低到androidx.navigation:navigation-compose:1.0.0-alpha09的评级。
