keyedFormBuilder function

Builder keyedFormBuilder(BuilderOptions options)

Builder factory for keyed_form_gen.

A PartBuilder (own .kfg.dart extension), NOT a SharedPartBuilder: the generated schema classes must be resolvable as a real source file before the shared-part phase runs, so that a @riverpod / dart_mappable signature is allowed to name one (KeyedFormController<ItineraryBuilderSchema>). A shared part would be materialised in the same phase and read back as an invalid type.

Implementation

Builder keyedFormBuilder(BuilderOptions options) {
  final formatter = DartFormatter(
    languageVersion: DartFormatter.latestLanguageVersion,
  );
  return PartBuilder(
    [const KeyedFormGenerator()],
    '.kfg.dart',
    // Puts the ignore-comment before `part of`, alongside the standard
    // "GENERATED CODE" banner — ahead of the generated body, so it survives
    // `dart format` untouched instead of drifting relative to whatever
    // follows it in the body.
    header:
        '// GENERATED CODE - DO NOT MODIFY BY HAND\n\n$generatedIgnoreComment',
    writeDescriptions: false,
    formatOutput: (code, version) {
      try {
        return formatter.format(code);
      } catch (_) {
        return code;
      }
    },
  );
}
