Row class final

A single query result row.

Implements Map<String, Object?> so you can use familiar map syntax:

final row = results[0];
print(row['name']);           // column access by name
print(row.containsKey('id')); // true
print(row.keys);              // column names

Rows are immutable views over the shared ResultSet values list. Use Map<String, Object?>.from(row) if you need a mutable copy.

Implements Map<String, Object?> for compatibility with standard Dart database patterns. Created lazily by ResultSet on access — not transferred across isolates.
