大家好,在这篇文章中,我们将学习如何添加动画,同时从一个页面到其他在 Flutter。我们将覆盖不同类型的动画和实现基本动画 Flutter 使用包页动画过渡。
动画在提升用户体验方面起着至关重要的作用,但动画到底是什么呢?
设计语言,例如 Material,定义了在路线(或屏幕)之间转换时的标准行为。不过,有时候,自定义屏幕之间的转换可以使应用程序更加独特。
在本教程中,我们将使用包页面 page_animation_transition 来简化在页面上添加转换。
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’) ;
