我正在制作一个项目，当用户单击按钮时，计时器将启动，在用户设置时间后，我正在使用 just_audio: ^0.6.15+1 播放声音在我的 flutter 项目中，但它导致下面的许多问题是错误的东西。

D/Linux   (21303): [Posix_connect Debug]Process com.snss.xlnc :443

var t = DateFormat.Hms().parse(time);
var rT = DateFormat.Hms().parse(remTime);

  player.setVolume(1);
  player.play();
  player.setLoopMode(LoopMode.one);
}

首先转到您的 AndroidManifest.xml。它可以在/android/app/src/main 中找到。
然后只需添加 android:usesCleartextTraffic="true"在 <application 下标签。
您的 AndroidManifest.xml 应如下所示

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="shafa_doctor"
        android:requestLegacyExternalStorage="true"
        android:usesCleartextTraffic="true" //just add this line only
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
