maybeSingle method

PostgrestTransformBuilder<PostgrestMap?> maybeSingle()

Retrieves at most one row from the result.

Result must be at most one row or nullable (e.g. using eq on a UNIQUE column or limit(1)), otherwise this will result in an error.

Implementation

PostgrestTransformBuilder<PostgrestMap?> maybeSingle() {
  // Temporary fix for https://github.com/supabase/supabase-flutter/issues/560
  // Issue persists e.g. for `.insert([...]).select().maybeSingle()`
  final newHeaders = {..._headers};

  if (_method?.toUpperCase() == 'GET') {
    newHeaders['Accept'] = 'application/json';
  } else {
    newHeaders['Accept'] = 'application/vnd.pgrst.object+json';
  }

  return PostgrestTransformBuilder(
    _copyWithType(
      maybeSingle: true,
      headers: newHeaders,
    ),
  );
}
