Declarative & implicit animations Library for Xamarin Forms. 

 

## Why Not `Xamarin.Forms.Animation`?

Xamarin Forms provides a common animation API, especially powerful with its `async`/`await` structure and extensibility. For many apps, it may be all that is necessary. **However**, it operates by setting up its own timing and modifying native view propertiies as it goes. This means the platform's hardware acceleration around animations can't be leveraged. Our experience was a sluggish feel that didn't "pop" the way a native app would.

## Example

To automatically animate the opacity of an element, simply add the transition to its attached property. Any property changes will then be animated according to the declaration.

```XML

xmlns:trans="clr-namespace:OliveTree.Transitions;assembly=OliveTree.Transitions"

  

    

      

    

  

  

    

      

    

  

```

Or triggered in code-behind:

```C#

StatusIndicator.Opacity = 0;

```

## Setup

For the common implementation to resolve platform animations, it must be given an `ITransitionProvider`. Each platform has one built in, but you are welcome to override it should needs arise. Generally, you will initialize it with:

```C#

Forms.Init();

TransitionsLibrary.Register();

```
