多個module之後, 如何管理依賴就是個問題.

關於幾種做法的總結: https://handstandsam.com/2018/02/11/kotlin-buildsrc-for-better-gradle-dependency-management/

Gradle 7.0 又出現了一種新方法:

enableFeaturePreview("VERSION_CATALOGS")

dependencyResolutionManagement {
  versionCatalogs {
    libs { 
      version('ver', '1.0.0')
      alias('my-alias').to('group', 'artifact').versionRef('ver')
      alias('another').to('group', 'artifact').versionRef('ver')
      bundle('my-bundle', ['my-alias', 'another']) 
   }
  }
}

val tasks by viewModel.getTasks().observeAsState(listOf())

LazyColumn(
    state = state.listState,
    modifier = Modifier
        .reorderable(state, { fromPos, toPos -> // 2.
            viewModel.onTaskReordered(tasks, fromPos, toPos)
        })
        .detectReorderAfterLongPress(state) // 3.
) {
    items(tasks, key = { task -> task.id }) { task ->
        Text(
            task.text,
            Modifier
                .draggedItem(state.offsetByKey(task.id)) // 4.
