# Animation Samples
Sample apps that showcasing Flutter's animation features
## Goals
- Demonstrate the building blocks for animations and how they work together
- Provide samples for common patterns and use-cases
## Samples
### Basics
Building blocks and patterns
1. **AnimatedContainerDemo** Demonstrates how to use `AnimatedContainer`
2. **PageRouteBuilderDemo** Demonstrates how to use `Tween` and `Animation` to
*build a custom page route transition.
3. **AnimationControllerDemo** Demonstrates how to use an `AnimationController`.
4. **TweenDemo** Demonstrates how to use a `Tween` with an
`AnimationController`.
5. **AnimatedBuilderDemo** Demonstrates how to use an `AnimatedBuilder` with an
`AnimationController`.
6. **CustomTweenDemo** Demonstrates how to extend `Tween`.
7. **TweenSequenceDemo** Demonstrates how to use `TweenSequence` to build a
button that changes between different colors.
### Misc
Other uses-cases and examples
- **RepeatingAnimationDemo** Demonstrates how to repeat an animation.
- **ExpandCardDemo** Demonstrates how to use `AnimatedCrossFade` to fade between
two widgets and change the size.
- **CarouselDemo** Demonstrates how to use `PageView` with a custom animation.
- **FocusImageDemo** Demonstrates how to measure the size of a widget and expand
it using a `PageRouteBuilder`.
- **PhysicsCardDragDemo** Demonstrates how to run an AnimationController with a
