大家好，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(xiàn)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(guān)重要的作用，但動畫到底是什么呢？

設計語言，例如 Material，定義了在路線(或屏幕)之間轉(zhuǎn)換時的標準行為。不過，有時候，自定義屏幕之間的轉(zhuǎn)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(zhuǎn)換。

使用插件探索不同的轉(zhuǎn)換

步驟 1: 在 pubspec.yaml 中添加頁面動畫轉(zhuǎn)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(zhuǎn)換到底轉(zhuǎn)換

RightToLeftTransition 右轉(zhuǎn)移

LeftToRightTransition 左/右轉(zhuǎn)變

FadeAnimationTransition 淡化動畫/轉(zhuǎn)換

ScaleAnimationTransition 標量動畫/轉(zhuǎn)換

RotationAnimationTransition 轉(zhuǎn)動/動畫/轉(zhuǎn)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(zhuǎn)到/ftfaded/transition

LeftToRightFadedTransition 左/右/插入/轉(zhuǎn)換

步驟3.添加以下導航代碼行

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

對于預定義的路由:

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:

輸出:
