get method

Future<String?> get(String url, Map<String, dynamic>? query)

Get cached response if fresh. Returns the cached body string or null if miss/stale.

Implementation

Future<String?> get(String url, Map<String, dynamic>? query) async {
  if (!db.initialized) return null;
  final key = _buildCacheKey(url, query);
  final cached = await db.getFromCache(key);
  if (cached == null) return null;
  final cachedAt = cached['cachedAt'] as int?;
  if (cachedAt == null) return null;
  final age = DateTime.now().millisecondsSinceEpoch - cachedAt;
  if (age <= config.maxAge.inMilliseconds) {
    return cached['body'] as String?;
  }
  if (config.maxStale != null && age <= (config.maxAge + config.maxStale!).inMilliseconds) {
    return cached['body'] as String?;
  }
  return null;
}
