Implementation

Builder jsonSerializable(BuilderOptions options) {
  try {
    var configJson = options.config;
    // Ignore `run_only_if_triggered` if present, it's used by `build_runner`.
    if (configJson.containsKey('run_only_if_triggered')) {
      configJson = Map.of(configJson)..remove('run_only_if_triggered');
    }
    final config = JsonSerializable.fromJson(configJson);
    return jsonPartBuilder(config: config);
  } on CheckedFromJsonException catch (e) {
    final lines = <String>[
      'Could not parse the options provided for `json_serializable`.',
    ];

    if (e.key != null) {
      lines.add('There is a problem with "${e.key}".');
    }
    if (e.message != null) {
      lines.add(e.message!);
    } else if (e.innerError != null) {
      lines.add(e.innerError.toString());
    }

    throw StateError(lines.join('\n'));
