Staggered Animation In Flutter

Staggered Animation in Flutter, “Staggered” means ‘moving in an unsteadily way whereas Staggered Animation is an animation that consists of sequential animations.

In this, all the animations are controlled with the help of a single Animation Controller.

This Animation Controller will handle multiple Animation objects in order to perform animations in order.

In order to set up the animation, we will have to follow a few steps:-

• Firstly, create an AnimationController that will manage all the animations.

• Now, create a Tween for each property being animated.
  • The Tween defines a range of values.
  • Tween’s animation method requires the parent controller and produces an Animation for that property.
• At last, specify the interval on the Animation’s Curve property.

Firstly, We will have to create Tween animation for all the properties which we want to animate, like this

Secondly, we have created a StaggeredWidget, which represents the widget we are animating.

In this, we are animating three properties of a container: height, width & opacity.

The AnimatedBuilder builds a widget and configures it by using the current values from the Tween. 

Most Importantly, it takes a parent controller and a builder widget for animation.
