在 android 上获取数据和缓存的最佳方法是什么？

Question

我目前正在使用google提供的算法networkboundresource，它有它的局限性，我想知道go的最佳方法是什么？

我想获取数据，缓存它并在新数据添加到服务器/远程数据库时更新缓存的数据

override suspend fun getSelectRoute(
        id: String,
        date: String,
        date2: String
    ): Flow<Resource<List<SelectRoute>>> {

        return networkBoundResource(
            query = {
                selectRouteEntityMapper.mapToDomainModelFlowList(selectRouteDao.getSelectRoute())
            },
            fetch = {
                selectRouteDtoMapper.mapToDomainModelList(
                    selectRouteService.getSelectRoute(
                        id = id,
                        date = date,
                        date2 = date2
                    )
                )
            },
            saveFetchResult = {
                actraDB.withTransaction {
                    selectRouteDao.deleteAllSelectRoute()
                    completedRoutesDao.deleteCompletedRoutes()
                    it.forEach {
                        selectRouteDao.insertSelectRoute(
                            selectRouteEntityMapper.mapFromDomainModel(it)
                        )
                        completedRoutesDao.insertCompletedRoute(
                            completedRoutesEntityMapper.mapFromDomainModel(it)
                        )
                        Log.d("repolist", "${it.address1}")
                    }
                }
            }
        )

inline fun <ResultType, RequestType> networkBoundResource(
    crossinline query: () -> Flow<ResultType>,
    crossinline fetch: suspend () -> RequestType,
    crossinline saveFetchResult: suspend (RequestType) -> Unit,
    crossinline shouldFetch: (ResultType) -> Boolean = { true }
) = flow {

    val data = query().first()

    val flow = if (shouldFetch(data)) {
        emit(Resource.Loading(data))
        try {
            saveFetchResult(fetch())
            query().map { Resource.Success(it) }
        } catch (throwable: Throwable) {
            query().map { Resource.Error(throwable.message, it) }
        }
    }else{
        query().map { Resource.Success(it) }
    }

    emitAll(flow = flow)

}
