flutter pub add flutter_visualizers根據套件公開資料產生的選型評估，僅供參考。
flutter_visualizers 是一個專為 Android 設備設計的 Flutter 插件，用於視覺化音訊播放。它提供音訊信號的即時視覺表示，非常適合音樂播放器或音訊分析應用。該插件利用 Android 內建的視覺化 API，直接在應用介面中渲染波形或頻譜圖。目前僅支援 Android，限制了其跨平台使用。開發者可透過 pub.dev 輕鬆整合，並自訂視覺風格以符合其應用設計。它透過在播放過程中提供動態音訊反饋來提升使用者參與度。

A Flutter plugin to Visualize the audio being played (only android).
Add this to your pubspec.yaml
dependencies:
flutter_visualizers: ^0.0.2
Get package from Pub:
flutter packages get
Import it in your file
import 'package:flutter_visualizers/flutter_visualizers.dart';
Firstly, get a audioSessionID from your native android Mediaplayer.
player.getAudioSessionId()
Simply Include this code in body
new Visualizer(
builder: (BuildContext context, List<int> wave) {
return new CustomPaint(
painter: new LineVisualizer(
waveData: wave,
height: MediaQuery.of(context).size.height,
width : MediaQuery.of(context).size.width,
color: Colors.blueAccent,
),
child: new Container(),
);
},
id: playerID,
)
Here playerId is the AudioSessionId which id needed to initialize the Visualizer. (Required Audio Recording Permission in Android)
