copyWith method

Script copyWith({ String? code, String? codeNumeric, String? date, String? name, String? pva, })

Creates a copy of this object with the given fields replaced with the new values.

For nullable fields, passing null leaves the field unchanged (standard Dart copyWith behavior). To explicitly reset a nullable field to null, pass a domain-invalid sentinel value:

• String? fields: pass an empty string (isEmpty) to reset to null.
• List? / Set? fields: pass an empty collection (isEmpty) to reset to null.
• double?/int? fields (positive-only, e.g. height/width/angle): pass a negative value (isNegative) to reset to null.

These sentinel values are never valid for the respective fields (enforced by constructor assertions), making the intent unambiguous.

Implementation

Script copyWith({
  String? code,
  String? codeNumeric,
  String? date,
  String? name,
  String? pva,
}) => ScriptCustom(
  code: code ?? this.code,
  name: name ?? this.name,
  codeNumeric: codeNumeric ?? this.codeNumeric,
  date: date ?? this.date,
  pva: (pva?.isEmpty ?? false) ? null : (pva ?? this.pva),
);
