loadLadderFixtures function

List<(String, List<Map<String, dynamic>>)> loadLadderFixtures(Directory dir)

Loads ladder fixture files from dir, returning sorted tier entries.

Each entry is a record of (tierName, fixtures) where fixtures is the decoded JSON list from that tier file.

Implementation

List<(String, List<Map<String, dynamic>>)> loadLadderFixtures(Directory dir) {
  final tierFiles = dir
      .listSync()
      .whereType<File>()
      .where((f) => f.path.endsWith('.json'))
      .toList()
    ..sort((a, b) => a.path.compareTo(b.path));

  return [
    for (final file in tierFiles)
      (
        file.uri.pathSegments.last.replaceAll('.json', ''),
        (jsonDecode(file.readAsStringSync()) as List)
            .cast<Map<String, dynamic>>(),
      ),
  ];
}
