getCachedOrFetch static method

Future<HttpResponse> getCachedOrFetch({ required String url, Map<String, String>? headers, dynamic body, required bool forceUpdate, required Duration ttl, required Future<HttpResponse> fetchFn(), })

Generic helper: check cache → fetch → cache result.

Implementation

static Future<HttpResponse<dynamic>> getCachedOrFetch({
  required String url,
  Map<String, String>? headers,
  dynamic body,
  required bool forceUpdate,
  required Duration ttl,
  required Future<HttpResponse<dynamic>> Function() fetchFn,
}) async {
  final cacheKey = generateCacheKeyForRequest(
    url: url,
    headers: headers,
    body: body,
  );

  // Check cache first
  if (!forceUpdate) {
    final cachedResponse = await getCachedResponse(
      cacheKey: cacheKey,
      forceUpdate: forceUpdate,
    );
    if (cachedResponse != null) {
      return cachedResponse;
    }
  }

  // Fetch fresh data
  final freshResponse = await fetchFn();

  // Cache if successful
  cacheIfSuccessful(
    cacheKey: cacheKey,
    response: freshResponse,
    ttl: ttl,
  );

  return freshResponse;
}
