putObject function

Implementation

Future<StorageMetadata> putObject(
  String path,
  Uint8List bytes, {
  String? contentType,
}) async {
  final p = path.toNativeUtf8();
  final type = (contentType ?? '').toNativeUtf8();
  // Copied into native memory for the call. The native side copies again for
  // the duration of the upload, because PutBytes does not take ownership and
  // completes long after this returns.
  final buf = calloc<Uint8>(bytes.isEmpty ? 1 : bytes.length);
  buf.asTypedList(bytes.length).setAll(0, bytes);
  try {
    final payload = await _awaitBuffer(
      (port) => fdbStoragePut(p.cast(), buf, bytes.length, type.cast(), port),
      'put $path',
    );
    return _decodeMetadata(payload);
  } finally {
    calloc
      ..free(p)
      ..free(type)
      ..free(buf);
