PrismDownloadManager class

Streams a file to disk with progress reporting and cancellation.

Used for direct downloads on platforms without a store flow (Windows, macOS, Linux, web-style links). Pure Dart — works everywhere.

final manager = PrismDownloadManager();
await for (final event in manager.download(
  url: Uri.parse('https://example.com/app.exe'),
  savePath: '/tmp/app.exe',
)) {
  if (event is PrismDownloadProgress) {
    print('${(event.fraction ?? 0) * 100}%');
  } else if (event is PrismDownloadComplete) {
    print('saved to ${event.file.path}');
  }
}
