Record audio in web and get the data

[ramakrishna-veli]

Hi Everyone I am using Record library for record audio messages and sent in my chat app using flutter, In mobile it's working completely fine because we have local storage but in web I am able to record the audio and send it in chat I am facing issues because it is giving some blob url as output path I am using getstream.io library for my chat application, this is the model of how to send audio message from web in Stream chat /// The class that contains the information about an attachment file
@JsonSerializable()
class AttachmentFile {
/// Creates a new [AttachmentFile] instance.
AttachmentFile({
required this.size,
this.path,
String? name,
this.bytes,
}) : assert(
path != null || bytes != null,
'Either path or bytes should be != null',
),
assert(
!CurrentPlatform.isWeb || bytes != null,
'File by path is not supported in web, Please provide bytes',
),
assert(
name?.contains('.') ?? true,
'Invalid file name, should also contain file extension',
),
_name = name;

/// Create a new instance from a json
factory AttachmentFile.fromJson(Map<String, dynamic> json) =>
_$AttachmentFileFromJson(json);

/// The absolute path for a cached copy of this file. It can be used to
/// create a file instance with a descriptor for the given path.
/// /// final File myFile = File(platformFile.path); ///
final String? path;

final String? _name;

/// File name including its extension.
String? get name =>
_name ?? path?.split(CurrentPlatform.isWindows ? r'' : '/').last;

/// Byte data for this file. Particularly useful if you want to manipulate
/// its data or easily upload to somewhere else.
@jsonkey(includeToJson: false, includeFromJson: false)
final Uint8List? bytes;

/// The file size in bytes.
final int? size;

/// File extension for this file.
String? get extension => name?.split('.').last;

/// The mime type of this file.
MediaType? get mediaType => name?.mediaType;

/// Serialize to json
Map<String, dynamic> toJson() => _$AttachmentFileToJson(this);

/// Converts this into a [MultipartFile]
Future toMultipartFile() async {
MultipartFile multiPartFile;

if (CurrentPlatform.isWeb) {
  multiPartFile = MultipartFile.fromBytes(
    bytes!,
    filename: name,
    contentType: mediaType,
  );
} else {
  multiPartFile = await MultipartFile.fromFile(
    path!,
    filename: name,
    contentType: mediaType,
  );
}
return multiPartFile;

}

/// Creates a copy of this [AttachmentFile] but with the given fields
/// replaced with the new values.
AttachmentFile copyWith({
String? path,
String? name,
Uint8List? bytes,
int? size,
}) {
return AttachmentFile(
path: path ?? this.path,
name: name ?? this.name,
bytes: bytes ?? this.bytes,
size: size ?? this.size,
);
}
} please help
