flutter pub add shaky_animated_listview基于插件公开信息、社区数据与项目使用情况整理的选型参考。
ShakyAnimatedListView 是一个 Flutter 包，可为动态列表项提供动画效果，以视觉方式跟踪滚动变化或列表项的初始出现。通过在项目进入视口或滚动过程中应用可自定义的过渡效果，它提升了用户体验。适用于创建具有流畅入场和移动动画的引人入胜、响应迅速的列表，支持 Android、iOS、Web、macOS、Windows 和 Linux 等多个平台。该包轻量且可无缝集成到现有的 Flutter 项目中。
以下为关联源码仓库的 README 原文快照，最新内容请访问源码仓库。
Shaky_animated_list can be used for three main things:
All these animations track your scroll changes on screen or your list first attachment to animated your list items with different transition rules.
| Shaking Grid | Scroll list | Scroll Grid |
|---|---|---|
 |
 |
 |
You can define these animation directions Axis by channing your list ScrollDirection.
Shaking grid can be simply implemented by wrapping your grid child by GridAnimatorWidget and that's it we will take it from here ^^
for example you can simply do this to show shaking grey color cards
GridView.count(
crossAxisCount: 3,
// shrinkWrap: true,
children: List.generate(9, (i) => GridAnimatorWidget(
child: Padding(
padding: const EdgeInsets.all(4),
child: ClipRRect(
borderRadius: const BorderRadius.all(Radius.circular(10)),
child: Container(
color: Colors.grey,
),
),
),
),).toList()
)
ListView Scroll animations will enable your to implement the scroll animations with full control on animations space and duration please don't add vertical margins to your elements, you can use the spaceBetween to give a space between elements and extendedSpaceBetween to control the scroll animations space.
Also you can use duration to control the reverse animations duration based on your needs
for example you can simply do this to show ListView vertical Scroll animations
AnimatedListView(
duration: 100,
extendedSpaceBetween: 30,
spaceBetween:10,
children: List.generate(
21,
(index) => Card(
elevation: 50,
margin: const EdgeInsets.symmetric(horizontal: 20),
shadowColor: Colors.black,
color: Colors.grey,
child: SizedBox(
height: 300,
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Column(
children: [
CircleAvatar(
backgroundColor: Colors.blue[500],
radius: 60,
child: const CircleAvatar(
backgroundImage: NetworkImage(
"https://avatars.githubusercontent.com/u/30810111?v=4"),
//NetworkImage
radius: 50,
),
),
const SizedBox(
height: 10,
),
Text(
'Scroll to start',
style: TextStyle(
fontSize: 30,
color: Colors.blue[900],
fontWeight: FontWeight.w500,
),
),
const SizedBox(
height: 10,
),
const Text(
'Animated list demo',
style: TextStyle(
fontSize: 15,
color: Colors.white,
),
),
const SizedBox(
height: 10,
),
],
),
),
),
)
))
Grid Scroll animations will enable your to implement the scroll animations on a grid view, one little change here is that we will implement the delegate, this is a design issue that we run into so you will have to
to specify your crossAxisCount, crossAxisSpacing, mainAxisSpacing, and duration and we will take it from here,you can use any other default supported parameters in GridView.
for example you can simply do this to show Grid vertical Scroll animations
AnimatedGridView(
duration: 100,
crossAxisCount: 2,
mainAxisExtent: 256,
crossAxisSpacing: 8,
mainAxisSpacing: 8,
children: List.generate(
21,
(index) => Card(
elevation: 50,
shadowColor: Colors.black,
color: Colors.grey[700],
child: SizedBox(
width: double.infinity,
child: Padding(
padding: const EdgeInsets.all(20.0),
child: Column(
children: const [
CircleAvatar(
backgroundColor: Colors.black,
radius: 60,
child: CircleAvatar(
backgroundImage: NetworkImage(
"https://avatars.githubusercontent.com/u/30810111?v=4"),
//NetworkImage
radius: 50,
),
),
],
),
),
),
)
)
),
if you want to add a horizontal animations, all what you have to do is to add a scroll direction to the widget and that's it for example you can simply do this to show ListView horizontal Scroll animations
AnimatedListView(
duration: 100,
scrollDirection: Axis.horizontal,
children: List.generate(
21,
(index) => const Card(
elevation: 50,
margin: EdgeInsets.symmetric(horizontal: 10),
shadowColor: Colors.black,
color: Colors.grey,
child: SizedBox(
height: 300,
width: 200,
),
),
),
),
