dispose method

void dispose()

Closes controllers and drops all state. The scope must not be reused.

Implementation

void dispose() {
  if (_disposed) return;
  _disposed = true;
  _cache.clear();
  for (final ctrl in _invalidationControllers.values) {
    try {
      ctrl.close();
    } catch (_) {}
  }
  _invalidationControllers.clear();
  _inFlightRequests.clear();
}
