Flutter/Dart - 如何使用 onPressed 和 flutter_Swiper 包中的 flatButton 播放列表中的聲音？

Question

G'day Stackoverflowers！

我已經開始為個人項目學習 Flutter/Dart，但遇到了一個我無法解決的問題。 我真的很感激一點幫助，請。

我正在構建一個學習英語的應用程序（我是一名英語老師和作家），該應用程序的其中一個頁面是您可以看到寫有名字的不同食物和飲料的圖片，以及聽發音的可能性食物或飲料。 這是到目前為止的代碼片段：

Swiper(
        itemWidth: MediaQuery.of(context).size.width,
        itemHeight: MediaQuery.of(context).size.height,
        layout: SwiperLayout.TINDER,
        itemCount: 43,
        indicatorLayout: PageIndicatorLayout.WARM,
        itemBuilder: (BuildContext context, int index,) {
          return Card(
            elevation: 5.0,
            child: Column(
              children: <Widget>[
                FlatButton(
                  onPressed: () => {
                    foodSounds[index],
                  },
                  child: Row(
                    children: <Widget>[
                      SizedBox(
                        width: 70.0,
                      ),
                      Icon(Icons.volume_up),
                      SizedBox(
                        width: 30.0,
                      ),
                      Text(foodNouns[index],
                          textAlign: TextAlign.center,
                          style: TextStyle(
                            fontSize: 20,
                            fontWeight: FontWeight.w500,
                          )),
                    ],
                  ),
                ),
                Image.asset(foodPictures[index], fit: BoxFit.contain),
              ],
            ),
          );

正如您可能猜到的那樣，我可以使用列表和該列表的索引來顯示我想要的圖片及其各自的名詞。 這是我為圖片和名詞准備的列表

final List foodPictures = [
'images/foodnouns/apple.jpg',
'images/foodnouns/banana.jpg',
'images/foodnouns/bar.jpg',
'images/foodnouns/beer.jpg',
'images/foodnouns/biscuits.jpg',
'images/foodnouns/bread.jpg',
'images/foodnouns/breakfast.jpg',
'images/foodnouns/butter.jpg',
'images/foodnouns/cafe.jpg',
'images/foodnouns/cake.jpg',
'images/foodnouns/cheese.jpg',
'images/foodnouns/chocolate.jpg',
'images/foodnouns/coffee.jpg',
'images/foodnouns/cup.jpg',
'images/foodnouns/cup_of_coffee.jpg',
'images/foodnouns/dinner.jpg',
'images/foodnouns/egg.jpg',
'images/foodnouns/fish.jpg',
'images/foodnouns/food.jpg',
'images/foodnouns/fries.jpg',
'images/foodnouns/fruits.jpg',
'images/foodnouns/glass.jpg',
'images/foodnouns/ice_cream.jpg',
'images/foodnouns/juice.jpg',
'images/foodnouns/knife.jpg',
'images/foodnouns/lunch.jpg',
'images/foodnouns/meal.jpg',
'images/foodnouns/meat.jpg',
'images/foodnouns/milk.jpg',
'images/foodnouns/orange.jpg',
'images/foodnouns/picnic.jpg',
'images/foodnouns/pizza.jpg',
'images/foodnouns/plate.jpg',
'images/foodnouns/potatoes.jpg',
'images/foodnouns/rice.jpg',
'images/foodnouns/salt.jpg',
'images/foodnouns/sandwich.jpg',
'images/foodnouns/soup.jpg',
'images/foodnouns/sugar.jpg',
'images/foodnouns/tea.jpg',
'images/foodnouns/tomato.jpg',
'images/foodnouns/vegetables.jpg',
'images/foodnouns/wine.jpg',];

final List foodNouns =[
'apple',
'banana',
'bar',
'beer',
'biscuits',
'bread',
'breakfast',
'butter',
'cafe',
'cake',
'cheese',
'chocolate',
'coffee',
'cup',
'cup_of_coffee',
'dinner',
'egg',
'fish',
'food',
'fries',
'fruits',
'glass',
'ice_cream',
'juice',
'knife',
'lunch',
'meal',
'meat',
'milk',
'orange',
'picnic',
'pizza',
'plate',
'potatoes',
'rice',
'salt',
'sandwich',
'soup',
'sugar',
'tea',
'tomato',
'vegetables',
'wine',];

這是到目前為止的樣子：

頁面概覽

現在我希望能夠為每張卡播放聲音。 我的資產中的聲音位於以下目錄中：資產：-assets/foodsounds/ 我希望能夠從我的聲音列表中播放聲音。 這是清單：

    final List foodSounds=[
  'assets/foodsounds/apple.mp3',
  'assets/foodsounds/banana.mp3',
  'assets/foodsounds/bar.mp3',
  'assets/foodsounds/beer.mp3',
  'assets/foodsounds/biscuits.mp3',
  'assets/foodsounds/bread.mp3',
  'assets/foodsounds/breakfast.mp3',
  'assets/foodsounds/butter.mp3',
  'assets/foodsounds/café.mp3',
  'assets/foodsounds/cake.mp3',
  'assets/foodsounds/cheese.mp3',
  'assets/foodsounds/chocolate.mp3',
  'assets/foodsounds/coffee.mp3',
  'assets/foodsounds/cup.mp3',
  'assets/foodsounds/cup_of_coffee.mp3',
  'assets/foodsounds/dinner.mp3',
  'assets/foodsounds/egg.mp3',
  'assets/foodsounds/fish.mp3',
  'assets/foodsounds/food.mp3',
  'assets/foodsounds/fries.mp3',
  'assets/foodsounds/fruits.mp3',
  'assets/foodsounds/glass.mp3',
  'assets/foodsounds/ice_cream.mp3',
  'assets/foodsounds/juice.mp3',
  'assets/foodsounds/knife.mp3',
  'assets/foodsounds/lunch.mp3',
  'assets/foodsounds/meal.mp3',
  'assets/foodsounds/meat.mp3',
  'assets/foodsounds/milk.mp3',
  'assets/foodsounds/orange.mp3',
  'assets/foodsounds/picnic.mp3',
  'assets/foodsounds/pizza.mp3',
  'assets/foodsounds/plate.mp3',
  'assets/foodsounds/potatoes.mp3',
  'assets/foodsounds/rice.mp3',
  'assets/foodsounds/salt.mp3',
  'assets/foodsounds/sandwich.mp3',
  'assets/foodsounds/soup.mp3',
  'assets/foodsounds/sugar.mp3',
  'assets/foodsounds/tea.mp3',
  'assets/foodsounds/tomato.mp3',
  'assets/foodsounds/vegetables.mp3',
  'assets/foodsounds/wine.mp3',];

我想過像這樣使用 audioplayers-0.14.0 包：

    void playFoodSound(int foodSounds) {
    final player = AudioCache(prefix: 'foodsounds/');
    player.play('$foodSounds.mp3');
  }

並在 Swiper 中使用它，如下所示：

FlatButton(
              onPressed: () => {
                foodSounds[index],
              },

這個方法行不通。 我嘗試了其他一些，但我真的不知道如何播放這些聲音......

非常感謝大家的幫助，因為我真的不想對這些聲音進行硬編碼。

Answer 1

原來我終於找到了我的答案。

我使用了 assets_audio_player 1.2.3 包。 聲明以下變量：

final AssetsAudioPlayer playFoodSound= AssetsAudioPlayer();

並在我的代碼中使用了以下語句：

FlatButton(onPressed: () =>{
                playFoodSound.open(foodSounds[index],),
          },

它就像一個魅力。
