shaking_grid scroll_list scroll_grid

You can define these animation directions Axis by channing your list ScrollDirection.

Shaking Grid

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

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

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, ), ), ], ), ), ), ) ) ),

ListView horizontal Scroll animations

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, ), ), ), ),
