Namespace

Code

public function render($row) {

  /* @var \Drupal\views\ResultRow $row */
  $geofield_value = $this->view
    ->getStyle()
    ->getFieldValue($row->index, $this->options['data_source']);
  if (empty($geofield_value)) {
    return FALSE;
  }

  // @TODO This assumes that the user has selected WKT as the geofield output
  // formatter in the views field settings, and fails otherwise. Very brittle.
  $result = $this->leafletService
    ->leafletProcessGeofield($geofield_value);

  // Convert the list of geo data points into a list of leaflet markers.
