evictCache<T, U extends JsonSerializable> method

Future<void> evictCache<T, U extends JsonSerializable>(GraphQLQuery<T, U> query)

Evicts (removes) cached data for a specific query.

Use this after mutations to invalidate stale cache entries.

Example:

// After updating user
await client.execute(UpdateUserMutation(...));
await client.evictCache(GetUserQuery(variables: GetUserArguments(id: '123')));

Implementation

Future<void> evictCache<T, U extends JsonSerializable>(
  GraphQLQuery<T, U> query,
) async {
  final request = Request(
    operation: Operation(
      document: query.document,
      operationName: query.operationName,
    ),
    variables: query.getVariablesMap(),
  );

  final cacheKey = _cacheLink.generateCacheKey(request);
  _cacheLink.evict(cacheKey);
}
