get method

String? get(
  1. String key
)

Returns the cached response for key, or null if expired or absent.

Implementation

String? get(String key) {
  final entry = _entries[key];
  if (entry == null) return null;
  if (entry.isExpired) {
    _entries.remove(key);
    return null;
  }
  // Move to end for LRU semantics.
  _entries.remove(key);
  _entries[key] = entry;
  return entry.response;
}
