resolve method

Future<List<Skill>> resolve(List<Skill> skills)

Resolve naming conflicts between skills

Groups skills by name and resolves conflicts by selecting the first occurrence of each duplicate name. In a full interactive version, this would prompt the user to choose between conflicting skills.

Args: skills: List of skills to resolve conflicts for

Returns: List of skills with conflicts resolved (no duplicate names)

Throws: ArgumentError: If skills list is null or contains null values

Implementation

Future<List<Skill>> resolve(List<Skill> skills) async {
  // In Dart's null safety, skills cannot be null and cannot contain null values
  // All skills are guaranteed to be non-null by the type system

  final grouped = <String, List<Skill>>{};

  for (final skill in skills) {
    grouped.putIfAbsent(skill.name, () => []).add(skill);
  }

  final resolved = <Skill>[];

  for (final entry in grouped.entries) {
    if (entry.value.length == 1) {
      resolved.add(entry.value.single);
    } else {
      // Conflict detected - user would need to choose
      // For now, take the first one
      resolved.add(entry.value.first);
    }
  }

  return resolved;
}
