這篇文章主要為大家介紹了Flutter添加頁(yè)面過(guò)渡動(dòng)畫，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進(jìn)步，早日升職加薪

正文

大家好，在這篇文章中，我們將學(xué)習(xí)如何添加動(dòng)畫，同時(shí)從一個(gè)頁(yè)面到其他在 Flutter。我們將覆蓋不同類型的動(dòng)畫和實(shí)現(xiàn)基本動(dòng)畫 Flutter 使用包頁(yè)動(dòng)畫過(guò)渡。

動(dòng)畫在提升用戶體驗(yàn)方面起著至關(guān)重要的作用，但動(dòng)畫到底是什么呢？

設(shè)計(jì)語(yǔ)言，例如 Material，定義了在路線(或屏幕)之間轉(zhuǎn)換時(shí)的標(biāo)準(zhǔn)行為。不過(guò)，有時(shí)候，自定義屏幕之間的轉(zhuǎn)換可以使應(yīng)用程序更加獨(dú)特。

在本教程中，我們將使用包頁(yè)面 page_animation_transition 來(lái)簡(jiǎn)化在頁(yè)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(yè)面動(dòng)畫轉(zhuǎn)換

page_animation_transition

步驟 2: 在 PageOne 上導(dǎo)入庫(kù)

假設(shè)您正在從 PageOne 過(guò)渡到 PageTwo

以下是圖書館支持的動(dòng)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(dòng)畫/轉(zhuǎn)換

ScaleAnimationTransition 標(biāo)量動(dòng)畫/轉(zhuǎn)換

RotationAnimationTransition 轉(zhuǎn)動(dòng)/動(dòng)畫/轉(zhuǎn)變

TopToBottomFadedTransition 上到下到過(guò)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(dǎo)航代碼行

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

對(duì)于預(yù)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:
