fromMapContent static method

Future<Deobfuscator> fromMapContent(String? content)

Loads the mapping data from content and uses it for a new Deobfuscator instance.

Returns an empty instance if no deobfuscation mapping is found. This allows caching of stripped generic types even in this case.

Implementation

static Future<Deobfuscator> fromMapContent(String? content) async {
  if (content == null) {
    // An empty deobfuscator will return obfuscated names with trimmed names
    // still cached.
    return Deobfuscator({});
  }

  final map = <String, String>{};

  final lines = content.split('\n');
  for (final line in lines) {
    final trimmedLine = line.trim();
    if (trimmedLine.isEmpty || trimmedLine.startsWith('#')) {
      continue;
    }

    final parts = trimmedLine.split('=');
    if (parts.length == 2) {
      final obfuscated = parts[0].trim();
      final deobfuscated = parts[1].trim();
      map[obfuscated] = deobfuscated;
    } else {
      Logger.log(
        LogLevel.debug,
        'Skipping malformed line in mapping file: $line',
      );
    }
  }

  return Deobfuscator(map);
