function hook_migrate_prepare_row

Allows adding data to a row before processing it.

For example, filter module used to store filter format settings in the variables table which now needs to be inside the filter format config file. So, it needs to be added here.

hook_migrate_MIGRATION_ID_prepare_row() is also available.

Parameters

\Drupal\migrate\Row $row: The row being imported.

\Drupal\migrate\Plugin\MigrateSourceInterface $source: The source migration.

\Drupal\migrate\Plugin\MigrationInterface $migration: The current migration.
