id3 #

A cross platform dart package to extract meta data from mp3 files.

This package contains functions that could extract meta tags from mp3 files that uses ID3 tag version 2.3.0 and ID3 tag version 1 to store meta data.

Usage #

import 'dart:io';
import 'package:id3/id3.dart';

void main(){
  List<int> mp3Bytes = File("./file.mp3").readAsBytesSync();
  MP3Instance mp3instance = new MP3Instance(mp3Bytes);

  /// parseTagsSync() returns 
  // 'true' if successfully parsed
  // 'false' if was unable to recognize tag so can't be parsed

  if(mp3instance.parseTagsSync()){
    print(mp3instance.getMetaTags());
  }
}

/// mp3instance.getMetaTags() returns Map<String, dynamic>
// {
//   "Title": "SongName",
//   "Artist": "ArtistName",
//   "Album": "AlbumName",
//   "APIC": {
//     "mime": "image/jpeg",
//     "textEncoding": "0",
//     "picType": "0",
//     "description": "description",
//     "base64": "AP/Y/+AAEEpGSUYAAQEBAE..."
//   }
// }

• MP3Instance used to take filename as string in v0.1, which is updated to take bytes as List<int> in v1.0

- MP3Instance mp3instance = new MP3Instance("./file.mp3");
+ List<int> mp3Bytes = File("./file.mp3").readAsBytesSync();
+ MP3Instance mp3instance = new MP3Instance(mp3Bytes);
