我正在尝试创建音乐应用程序使用just_audio & just_audio_background插件，应用程序运行正常，但我正在尝试从flutter_stripe插件集成Stripe。我在点击结帐按钮时收到异常。它看起来像just_audio_background中的类com.ryanheise.audioservice.AudioServiceActivity与flutter_stripe插件冲突

异常您的主活动类com.ryanheise.audioservice.AudioServiceActivity不是一个子类FlutterFragmentActivity。
主要活动.kt

package com.example.spotify
import io.flutter.embedding.android.FlutterActivity
import io.flutter.embedding.android.FlutterFragmentActivity
class MainActivity: FlutterFragmentActivity() {
}
