Null-Safety checked!

An animation package inspired in Animate.css, built using only Flutter animations, no extra packages.

Getting Started

This package is simple to use. Every single animation contains default values that look beautiful, but you can change properties to accomplish your needs.

Properties in almost every animated widget:

Property	Type	Description
key	Key	(optional) Widget key
child	Widget	Child Widget to animate
duration	Duration	Animation duration
delay	Duration	Delay before the animation
from	double	Initial or final destination, if you want a slide or fade more striking
animate	boolean	Change this property from false to true to starts the animation (useful if you use setState, Bloc, Provider, Redux or any other state management system)
infinite	boolean	Attention seekers can be run infinitely with this property
spins	double	The number of spins that you want (some animations have this, ex: Spin, Roulette, PerfectSpin )
manualTrigger	boolean	if you're going to trigger the animation manually (required the controller property)
controller	Function	Function that exposes the controller (for more control of the animation

        ),

    ),
),

Example Basic #2 - Now with Toggle

Just toggle the animate property to animate in or out easily. Check the full code inside the example folder

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  
  bool launchAnimation = false;

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Material App',
      home: Scaffold(
        body: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            
            const Text('Now with a simple Toggle', style: TextStyle(fontSize: 20),),
            Text('Boolean animate value: $launchAnimation' ),
            const SizedBox(height: 20 ),

            Row(
              mainAxisAlignment: MainAxisAlignment.spaceAround,
              children: <Widget>[
                FadeIn(child: const Square(), animate: launchAnimation,),
                FadeInUp(child: const Square(), animate: launchAnimation,),
                FadeInDown(child: const Square(), animate: launchAnimation,),
                FadeInLeft(child: const Square(), animate: launchAnimation,),
                FadeInRight(child: const Square(), animate: launchAnimation,),
                
              ],
            ),

            const SizedBox(height: 20 ),

            ElevatedButton(onPressed: () {
              setState(() {
                launchAnimation = !launchAnimation;
              });
            }, child: const Text('Toggle animation'))
          ],
        ),
      ),
    );
  }
}

Note: Square, is just a Square blue container

class Square extends StatelessWidget {

  @override
  Widget build(BuildContext context) {
    return Container(
      width: 50,
      height: 50,
      decoration: BoxDecoration(
        color: Colors.blueAccent,
      ),
    );
  }
}

Manual Trigger

Since version 1.2.0, there is a way to get the AnimationController easily, so you can restart it, change the duration, do the animation again.

Example

  class FadeOutDownBig extends StatelessWidget/StatefulWidget {
  
  AnimationController animateController;
  ...
  ...
  ...

  child: FadeInUp(
    
    // (optional) if true, will not fire the animation on load
    manualTrigger: true, 

    //(optional, but mandatory if you use manualTrigger:true) This callback exposes the AnimationController used for the selected animation. Then you can call animationController.forward() to trigger the animation wherever you like manually.
    controller: ( controller ) => animateController = controller,

    child: YourWidget(),
