AddColumn(String name, { Object? defaultValue, Object? compute(Map<String, dynamic> row)?, bool overwrite = false, String? sqlType, String? sqlExpression, })

Implementation

AddColumn(
  this.name, {
  this.defaultValue,
  this.compute,
  this.overwrite = false,
  this.sqlType,
  this.sqlExpression,
}) : assert(
        defaultValue == null || compute == null,
        'Provide either defaultValue or compute for "$name", not both.',
      );
