Jetpack Compose Material3中rememberDismissState引用未解决求助

出现该错误的核心原因是依赖配置、导入语句或版本兼容问题，以下是具体解决步骤：

1. 确认Material3依赖版本 #

在Module级的build.gradle（或build.gradle.kts）文件中，确保引入的Material3版本满足要求（建议使用1.1.0及以上稳定版），示例配置如下：

dependencies {
    // 替换为项目适配的最新Material3稳定版
    implementation("androidx.compose.material3:material3:1.2.0")
}

2. 添加缺失的导入语句 #

rememberDismissState属于androidx.compose.material3包下的Experimental API，需要在代码顶部补充导入：

import androidx.compose.material3.rememberDismissState

3. 同步并重建项目 #

完成上述操作后，点击Android Studio右上角的Sync Now同步Gradle依赖，再依次执行Build -> Clean Project和Build -> Rebuild Project，确保依赖正确加载。
