颤振:按下按钮时播放声音 [英] Flutter: Play sound on button press

问题描述

我对编程非常陌生，尤其是颤抖.我想写一个音板，基本上是一个按钮列表，每个按钮的工作是播放我在PC上按下时发出的声音.我已经使用列表视图和一些素材按钮完成了设计，但是我不知道如何在按下它们时使它们播放声音.有人可以帮我吗?

I'm very new to programing and especially flutter. I want to write an soundboard, basically a list of buttons and the job of each button is to play a sound that i have on my PC when they are pressed. I've already done the design with a list view and some material buttons but I don't know how to make them play sounds when I press them. Can some one help me?
