要在更改屏幕时播放动画，我正在使用page_transition: ^1.1.5

这是一个例子：

Navigator.push(context, PageTransition(type: PageTransitionType.rightToLeft, child: HandymanDocumentsOverview(), duration: Duration(milliseconds: 150)));

昨天我安装firebase_core: ^0.5.0并更新了所有其他 Firebase 依赖项。不知何故，感觉动画速度Navigator.pop(context);比以前慢了很多，甚至不匹配第一个动画速度。有谁知道如何解决这个问题？

编辑这里是我的flutter doctor -v

您正在使用的包尚未更新以设置reverseTransitionDuration最近添加到颤振的包。您可以对此问题进行投票以引起人们的注意。

这是指定正向和反向持续时间的一种方法：

Navigator.of(context).push(
  PageRouteBuilder(
    transitionDuration: Duration(milliseconds: 800), // Forward Duration
    reverseTransitionDuration: Duration(milliseconds: 800), // Reverse Duration
    pageBuilder: (BuildContext context,
        Animation<double> animation,
        Animation<double> secondaryAnimation) {
      return NewScreen();
    },
    transitionsBuilder: (BuildContext context,
        Animation<double> animation,
        Animation<double> secondaryAnimation,
        Widget child) {
      return FadeTransition(
        opacity: animation,
        child: child,
      );
    },
  ),
);
