Flutter怎么实现添加页面过渡动画

本篇内容介绍了"Flutter怎么实现添加页面过渡动画"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

使用插件探索不同的转换

步骤 1: 在 pubspec.yaml 中添加页面动画转换

page_animation_transition

步骤 2: 在 PageOne 上导入库

假设您正在从 PageOne 过渡到 PageTwo

以下是图书馆支持的动画类型:

BottomToTopTransition TopToBottomTransition 底到上转换到底转换

RightToLeftTransition 右转移

LeftToRightTransition 左/右转变

FadeAnimationTransition 淡化动画/转换

ScaleAnimationTransition 标量动画/转换

RotationAnimationTransition 转动/动画/转变

TopToBottomFadedTransition 上到下到过渡

BottomToTopFadedTransition 底部/上部/下部/上部/下部/上部/下部/上部/下部/上部/下部/上部/

RightToLeftFadedTransition 右转到/ftfaded/transition

LeftToRightFadedTransition 左/右/插入/转换

步骤3.添加以下导航代码行

Navigator.of(context).push(PageAnimationTransition(page: const PageTwo(), pageAnimationType: BottomToTopTransition()));

对于预定义的路由:

onGenerateRoute: (settings) {    switch (settings.name) {      case '/pageTwo':        return PageAnimationTransition(child: PageTwo(), pageAnimationType: LeftToRightFadedTransition());        break;      default:        return null;    }  }

Navigator.pushNamed(context, '/pageTwo');

Pushnamed (context,’/pageTwo’) ;

Output:
