Flutter添加頁面過渡動畫實現步驟
正文
大傢好,在這篇文章中,我們將學習如何添加動畫,同時從一個頁面到其他在 Flutter。我們將覆蓋不同類型的動畫和實現基本動畫 Flutter 使用包頁動畫過渡。
動畫在提升用戶體驗方面起著至關重要的作用,但動畫到底是什麼呢?
設計語言,例如 Material,定義瞭在路線(或屏幕)之間轉換時的標準行為。不過,有時候,自定義屏幕之間的轉換可以使應用程序更加獨特。
在本教程中,我們將使用包頁面 page_animation_transition 來簡化在頁面上添加轉換。
使用插件探索不同的轉換
步驟 1: 在 pubspec.yaml 中添加頁面動畫轉換
page_animation_transition
步驟 2: 在 PageOne 上導入庫
假設您正在從 PageOne 過渡到 PageTwo
以下是圖書館支持的動畫類型:
BottomToTopTransition TopToBottomTransition 底到上轉換到底轉換
RightToLeftTransition 右轉移
LeftToRightTransition 左/右轉變
FadeAnimationTransition 淡化動畫/轉換
ScaleAnimationTransition 標量動畫/轉換
RotationAnimationTransition 轉動/動畫/轉變
TopToBottomFadedTransition 上到下到過渡
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 右轉到/ftfaded/transition
LeftToRightFadedTransition 左/右/插入/轉換
步驟3.添加以下導航代碼行
Navigator.of(context).push(PageAnimationTransition(page: const PageTwo(), pageAnimationType: BottomToTopTransition()));
對於預定義的路由:
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:
