我已连接到Firebase实时数据库：

数据：

data class Settings(
    val light_on: Boolean = false,
    val door_open: Boolean = false,
    val window_open: Boolean = false
)

仓库编码：

class SettingsRepository @Inject constructor() {
    private val database: FirebaseDatabase = DatabaseModule.getFirebaseDatabaseInstance()

    fun getSettings() : Flow<HomeSettings?> {
        return callbackFlow {
            val dataRef = database.getReference("settings")

            val listener = dataRef.addValueEventListener(object: ValueEventListener {
                override fun onDataChange(snapshot: DataSnapshot) {
                   trySend(snapshot.getValue(HomeSettings::class.java))
                }

                override fun onCancelled(error: DatabaseError) {
                    cancel()
                }
            })

            awaitClose { dataRef.removeEventListener(listener) }
        }
    }

    fun createData(settings: Settings) : Flow<Settings> = flow {
        database.reference.child("settings").setValue(settings).await()
    }

    fun updateLightState(settings: Settings) : Flow<Settings> = flow {
        database.reference.child("settings").setValue(settings).await()
    }

    fun updateDoorState(settings: Settings) : Flow<Settings> = flow {
        database.reference.child("settings").setValue(settings).await()
    }

    fun updateWindowState(settings: Settings) : Flow<Settings> = flow {
        database.reference.child("settings").setValue(settings).await()
    }
}

用法：

fun createData(){
    settingsRepository.createData(settings.value)
}

LaunchedEffect(scope) {
    viewModel.createData()
}

它只是不显示任何在实时数据库Firebase控制台在线在谷歌，这是奇怪的。没有错误打印在调试输出在Android Studio。我只是不明白为什么这不工作。

编辑：规则没有问题，已更改。

**EDIT：**这个是我自己做的，在控制台显示的是引用的名称，不是项目，需要手动设置ID，还是做一些配置修改？

fun insert(item: Settings) : Flow<ResultResponse<String>> = callbackFlow {
        trySend(ResultResponse.Loading)

        reference.push().setValue(item)
            .addOnCompleteListener {
                if(it.isSuccessful)
                    trySend(ResultResponse.Success("Data inserted successfully"))
            }
            .addOnFailureListener {
                trySend(ResultResponse.Failure(it))
                cancel()
            }

        awaitClose { close() }
    }
