fromMediaItem static method

Future<AttachedFile> fromMediaItem(MediaItem mediaItem)

Creates an AttachedFile from a MediaItem.

If the MediaItem was created using MediaItem.fromNetwork and doesn't have bytes yet, this method will fetch the file from the network URL.

Example:

final mediaItem = MediaItem.fromNetwork('https://example.com/image.png');
final attachedFile = await AttachedFile.fromMediaItem(mediaItem);

Implementation

static Future<AttachedFile> fromMediaItem(MediaItem mediaItem) async {
  // If bytes are already present (e.g., from MediaItem.fromFile), use them directly
  if (mediaItem.bytes != null) {
    return AttachedFile._(mediaItem);
  }

  // If no bytes, fetch from the network URL
  final uri = Uri.parse(mediaItem.url);
  final response = await http.get(uri);

  // Extract filename from the URL or use a default
  final name =
      uri.pathSegments.isNotEmpty ? uri.pathSegments.last : 'file.txt';

  // Create a new MediaItem with the fetched bytes and attachment:// URL
  final media = MediaItem.fromNetwork(
    'attachment://$name',
    spoiler: mediaItem.spoiler,
    proxyUrl: mediaItem.proxyUrl,
    height: mediaItem.height,
    width: mediaItem.width,
    contentType: mediaItem.contentType,
    description: mediaItem.description,
  )..bytes = response.bodyBytes;

  return AttachedFile._(media);
