Flutter添加页面过渡动画实现步骤

正文

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’) ;
