Implementation

First of all, we need to create a new flutter project.

After that, we need to create a StatefulWidget(AnimatedBuilderPage), and call it from the main dart.

Now we need to create the UI of AnimatedBuilderPage, so we add the following code inside the AnimatedBuilderPage class.

AnimationController:->This is a controller for an animation.

AnimationController class lets you perform tasks such as:

1)Play an animation forward or reverse or stop an animation.

2)Set the animation to a specific value.

3)Define the UpperBound and LowerBound Value for animation.

4)Create a filing animation effect using a physics simulation.

The AnimatedBuilder have two argument field is required must not be empty, the first one is animation and the second one is builder and the child is optional which can pass or not.

 

Now above is the Output of the Code.
