computeHash method

String computeHash()

Computes the canonical deterministic SHA-256 runtime fingerprint hash string.

Implementation

String computeHash() {
  final buffer = StringBuffer();
  buffer.writeln('bloom_version:$bloomVersion');
  buffer.writeln('flutter_engine:$flutterEngineRevision');
  buffer.writeln('dart_sdk:$dartSdkVersion');

  // Sort native modules deterministically
  final sortedModules = nativeModuleFingerprints.keys.toList()..sort();
  for (final mod in sortedModules) {
    buffer.writeln('module:$mod:${nativeModuleFingerprints[mod]}');
  }

  // Sort permissions deterministically
  final sortedPerms = List<String>.from(permissions)..sort();
  for (final p in sortedPerms) {
    buffer.writeln('permission:$p');
  }

  return sha256.convert(utf8.encode(buffer.toString())).toString();
}
