如何使用 Swiper(Slider) 在颤动中映射或索引图像和音频？

如何解决如何使用 Swiper(Slider) 在颤动中映射或索引图像和音频？

如何在Flutter中映射或索引图像和音频

我正在尝试制作滑块应用程序如果滑块打开播放音频

我被存储了 26 个图像和 26 个音频

如果第一张幻灯片打开播放第一个音频和第二个图像第二个音频

我正在使用 Swiper Flutter_swiper：用于滑动滑块的 ^1.1.4 设置为自动播放

我正在使用音频播放器 assets_audio_player: ^2.0.10

我正在尝试制作完整的离线应用，所以我使用 assets_audio_player：^2.0.10

import 'package:Flutter/material.dart';
 import 'package:Flutter_swiper/Flutter_swiper.dart';
 import 'package:assets_audio_player/assets_audio_player.dart';
