是否可以将 Flow 与 Room 删除或插入操作一起使用，因为它在 RxJava 中使用 Single 或 Maybe that returns row ids？

Question

通话中

@Insert(onConflict = OnConflictStrategy.REPLACE)
fun insert(entity: PostEntity): Flow<Long>
   
@Delete
fun deletePost(entity: PostEntity): Flow<Long>

returns编译错误

 Not sure how to handle insert method's return type.
    public abstract kotlinx.coroutines.flow.Flow<java.util.List<java.lang.Long>> insertFlow(@org.jetbrains.annotations.NotNull()

不能像在 RxJava 中那样使用带有 Int 或 long 的 Flow 来获取数据库操作结果的 ID 吗？

@Insert(onConflict = REPLACE)
fun insert(entity: T): Maybe<Long>

@Insert(onConflict = REPLACE)
fun insert(entity: T): Single<Long>

Answer 1

根据 Async queries with Kotlin coroutines in Room，Kotlin 协程中 Maybe 和 Single 的等价物是 suspend:

@Insert(onConflict = OnConflictStrategy.REPLACE)
suspend fun insert(entity: PostEntity): Long

@Delete
suspend fun deletePost(entity: PostEntity): Long

Is it possible to use Flow with Room delete or insert operations as it's used in RxJava with Single or Maybe that returns row ids?
