问题描述

我第一次使用Jetpack Compose，但出现此错误.我还没有弄清楚问题出在哪里，但我使用的是单活动架构.如果需要更多信息，请通知我.根据错误，问题似乎出在脚手架上.

I'm using Jetpack Compose for the first time but I'm getting this error. I haven't figured out where the problem really is but I'm using single-activity architecture. If more information is needed, kindly inform me. According to the error, the problem seems to be coming from the Scaffold.

                val scaffoldState = rememberScaffoldState()

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

推荐答案

此答案基于CommonsWare注释，可帮助我修复错误.

This answer is based on CommonsWare comment which helped me fix the error.

解决方案是使用一组一致的Compose依赖项.beta04在撰写基础工件中对BoxScope进行了更改.也许您正在获得该工件的beta04，但获得的是旧的撰写材料工件.

The solution was to use a consistent set of Compose dependencies. beta04 made a change to BoxScope in the compose-foundation artifact. Perhaps you are getting beta04 of that artifact but are getting an older compose-material artifact.
