按下按钮时的动画文本过渡

如何解决按下按钮时的动画文本过渡

我有 3 种引号。当按下相应的按钮时，如果引用从类别 1 到类别 2 再到类别 3，则引用会消失，反之亦然。

但是，即使它们来自同一类别，我也想让引用消失。现在，当引用来自不同类别时，它会消失。

这怎么可能？谢谢

我认为这与按钮有关。例如。当按下猫 1 的按钮时，猫 1 的引用的不透明度变为 0 并返回 1（持续时间为一秒）。 但我不知道怎么写。

下面附上此操作中涉及的主要代码块：

  double opacity1 = 0.0;
  double opacity2 = 0.0;
  double opacity3 = 0.0;

String quoteCat1 = List1[Random().nextInt(List1.length)];

  void generateConvoTopic1() {
    setState(() {
      quoteCat1 = List1[Random().nextInt(List1.length)];
    });
  }

  String quoteCat2 = List2[Random().nextInt(List2.length)];

  void generateConvoTopic2() {
    setState(() {
      convoTopic2 = List2[Random().nextInt(List2.length)];
    });
  }

  String quoteCat3 = List3[Random().nextInt(List3.length)];

  void generateConvoTopic3() {
    setState(() {
      quoteCat3 = List3[Random().nextInt(List3.length)];
    });
  }

 @override
  Widget build(BuildContext context) {
   
    return Scaffold(

///Following are where the quotes are stacked. But they take  turns to show their opacity.

Stack(children: <Widget>[
              
                AnimatedOpacity(
                    opacity: opacity1,duration: Duration(seconds: 1),child:Text(quoteCat1),AnimatedOpacity(
                    opacity: opacity2,child: Text(quoteCat2),AnimatedOpacity(
                    opacity: opacity3,child: Text(quoteCat3),]),...

                      opacity2 = 0.0;
                      opacity3 = 0.0;
                    },),ElevatedButton(
