Field support request: Nova Stack field

[marcobax]

When using a Nova Stack field and exporting a Nova resource to Excel the value inside the cell is empty

Example field:

  Stack::make(__('Stack field'), [
      Text::make(__('Some value'), 'some.value'),
      Text::make(__('Something else'), 'something.else'),
]),

In the file:

Maatwebsite\LaravelNovaExcel\Actions inside the method replaceFieldValuesWhenOnResource the values are resolved using $field->value. This will output NULL in case of a Stack field.

It would be nice to have all of the fields inside a Stack field to be automatically flattened. I've solved it (in my index fields) by adding this:

foreach ($fields as $index => $field)
  if ($field->component === 'stack-field' && $field->lines) {
      unset($fields[$index]);
  
      foreach ($field->lines as $item => $line) {
          $fields = array_merge(array_slice($fields, 0, $index + $item), [$line], array_slice($fields, $index + $item));
      }
  }
}

Kind regards,

Marco
