flutter_media_metadata_new

flutter_media_metadata_new is a Flutter package that allows you to extract media metadata (such as track name, artist, album, duration, etc.) from audio and video files on both Android and iOS platforms.

Features

• Retrieve media metadata like track name, artist names, album name, and more.
• Access album art as Uint8List for display.
• Get file information such as duration, bitrate, and MIME type.
• Platform-specific implementations for Android and iOS using native APIs.

Installation

Add flutter_media_metadata_new to your pubspec.yaml file:

dependencies:
  flutter_media_metadata_new: ^0.0.1

Then, run flutter pub get to install the package.

Usage

1. Import the Package

import 'package:flutter_media_metadata_new/flutter_media_metadata_new.dart';

2. Extract Metadata from a Media File You can extract metadata from a media file by calling FlutterMediaMetadataNew.getMetadata with the file path:

import 'package:flutter/material.dart';
import 'package:flutter_media_metadata_new/flutter_media_metadata_new.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  FileMetaData? fileMetadata;

  @override
  void initState() {
    super.initState();
    loadMetadata();
  }

  Future<void> loadMetadata() async {
    final path = '/path/to/your/media/file.mp3'; // Provide the path to your media file
    final fileMetadata = await FlutterMediaMetadataNew.getMetadata(path);
    setState(() {
      this.fileMetadata = fileMetadata;
    });
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Media Metadata Example'),
        ),
        body: Center(
          child: fileMetadata == null
              ? CircularProgressIndicator()
              : Text('Track Name: ${fileMetadata!.trackName}\n'
                  'Artist: ${fileMetadata!.trackArtistNames?.join(", ")}\n'
                  'Album: ${fileMetadata!.albumName}'),
        ),
      ),
    );
  }
}

3. FileMetaData Model The FileMetaData class contains various fields for the media information:

class FileMetaData {
  final String? trackName;
  final List<String>? trackArtistNames;
  final String? albumName;
  final String? albumArtistName;
  final int? trackNumber;
  final int? albumLength;
  final int? year;
  final String? genre;
  final String? authorName;
  final String? writerName;
  final int? discNumber;
  final String? mimeType;
  final int? trackDuration;
  final int? bitrate;
  final Uint8List? albumArt;
  final String? filePath;

  FileMetaData({
    this.trackName,
    this.trackArtistNames,
    this.albumName,
    this.albumArtistName,
    this.trackNumber,
    this.albumLength,
    this.year,
    this.genre,
    this.authorName,
    this.writerName,
    this.discNumber,
    this.mimeType,
    this.trackDuration,
    this.bitrate,
    this.albumArt,
    this.filePath,
  });
}

Example Metadata Fields:

• trackName: The name of the track.
• trackArtistNames: A list of artist names.
• albumName: The name of the album.
• albumArtistName: The name of the album artist.
• trackNumber: The position of the track in the album.
• albumLength: The number of tracks in the album.
• year: The year the track was released.
• genre: The genre of the track.
• authorName: The author of the track.
• writerName: The writer of the track.
• discNumber: The disc number in a multi-disc set.
• mimeType: The MIME type of the file.
• trackDuration: The duration of the track in milliseconds.
• bitrate: The bitrate of the track.
• albumArt: The album art as a Uint8List.
• filePath: The file path of the media file.

Platform-Specific Details

Android The package uses MediaMetadataRetriever to extract metadata from media files.

iOS The package uses AVFoundation to extract metadata from media files.
