Audio constructor

const Audio({ @JsonKey(name: 'file_id') required String fileId, @JsonKey(name: 'file_unique_id') required String fileUniqueId, @JsonKey(name: 'duration') required int duration, @JsonKey(name: 'performer') String? performer, @JsonKey(name: 'title') String? title, @JsonKey(name: 'file_name') String? fileName, @JsonKey(name: 'mime_type') String? mimeType, @JsonKey(name: 'file_size') int? fileSize, @JsonKey(name: 'thumbnail') PhotoSize? thumbnail, })

Creates a new Audio object.

Implementation

const factory Audio({
  /// Identifier for this file, which can be used to download or reuse the
  /// file
  @JsonKey(name: 'file_id') required String fileId,

  /// Unique identifier for this file, which is supposed to be the same over
  /// time and for different bots. Can't be used to download or reuse the
  /// file.
  @JsonKey(name: 'file_unique_id') required String fileUniqueId,

  /// Duration of the video in seconds as defined by sender
  ///
  /// A handy [Duration] getter is available as [durationTime]
  @JsonKey(name: 'duration') required int duration,

  /// Optional. Performer of the audio as defined by sender or by audio tags
  @JsonKey(name: 'performer') String? performer,

  /// Optional. Title of the audio as defined by sender or by audio tags
  @JsonKey(name: 'title') String? title,

  /// Optional. Original filename as defined by sender
  @JsonKey(name: 'file_name') String? fileName,

  /// Optional. MIME type of the file as defined by sender
  @JsonKey(name: 'mime_type') String? mimeType,

  /// Optional. File size in bytes. It can be bigger than 2^31 and some
  /// programming languages may have difficulty/silent defects in interpreting
  /// it. But it has at most 52 significant bits, so a signed 64-bit integer
  /// or double-precision float type are safe for storing this value.
  @JsonKey(name: 'file_size') int? fileSize,

  /// Optional. Thumbnail of the album cover to which the music file belongs
  @JsonKey(name: 'thumbnail') PhotoSize? thumbnail,
