+# Animation Samples
+Sample apps that showcase 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.
+8. **FadeTransitionDemo**: Demonstrates how to use `FadeTransition`.
+
+### 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
+  spring simulation.
+- **CardSwipeDemo**: A swipeable card that demonstrates how to use gesture
+  detection to drive an animation.
+- **AnimatedList**: Demonstrates how to use `AnimatedList`.
+- **AnimatedPositionedDemo**: Demonstrates how to use `AnimatedPositioned`.
+- **AnimatedSwitcherDemo**: Demonstrates how to use `AnimatedSwitcher`.
+- **HeroAnimationDemo**: Demonstrates how to use `Hero` animation.
+- **CurvedAnimationDemo**: Demonstrates how to use different curves in
+  `CurvedAnimation`.
