real function
A floating-point column.
name fixes the physical column name; otherwise snake_case is derived from
the Record field. defaultSql is trusted database SQL. clientDefault runs
only for omitted insert values and may coexist with a database default.
Implementation
ColumnDefinition<double> real({
String? name,
bool unique = false,
double? defaultValue,
String? defaultSql,
double Function()? clientDefault,
}) => const ColumnDefinition._();
