Learn Performing Animation in .NET MAUI Part 1

Learn Performing Animation in .NET MAUI: Part 1

According to Wikipedia, “Animation is a method in which figures are manipulated to appear as moving objects.” Animation in an app is essential to provide an appealing UI and better responsiveness. A cross-platform application like a .NET Multi-platform App UI (.NET MAUI) app also needs animation to make it more attractive.

Two kinds of animation can be applied in .NET MAUI:

  • Basic animations
  • Lottie animations

In this blog, let’s take a quick look at these animation methods.

.NET MAUI basic animation

As stated in the Microsoft documentation, “The .NET Multi-platform App UI (.NET MAUI) animation classes target different properties of visual elements, with a typical basic animation progressively changing a property from one value to another over a period of time.”

Built-in animations

There are four basic built-in animations available in .NET MAUI:

  • Fade
  • Rotation
  • Scale
  • Translate

 Fade

Fade animation can fade in and fade out a view by changing the opacity. Refer to the following code example.

this.fadeInImage.Opacity = 0;

//Fade in
await this.fadeInImage.FadeTo(1, 2000);

//Fade out
await this.fadeInImage.FadeTo(0, 2000);

Rotation

Rotate a view using the Rotate support. You can use general, vertical, horizontal, or relative rotation.

Refer to the following code example.

this.rotateImage.Rotation = 0;

// General rotation
await this.rotateImage.RotateTo(360, 2000);

// Vertical rotation
await this.rotateImage.RotateXTo(360 , 2000);

// Horizontal rotation
await this.rotateImage.RotateYTo(360, 2000);

Note: We can also rotate horizontally, vertically, and relatively using the RotateXTo, RotateYTo, and RelRotateTo APIs, respectively.

Scale

We can scale a view using the Scale property. There are four types of scaling: vertical, horizontal, aspect, and relative.

Refer to the following code example.

// Zoom in
await this.scaleImage.ScaleTo(1, 2000);

// Zoom out
await this.scaleImage.ScaleTo(0, 2000);

// Horizontal scaling
await this.scaleImage.ScaleXTo(1, 2000);
await this.scaleImage.ScaleXTo(0, 2000);

// Vertical scaling
await this.scaleImage.ScaleYTo(1, 2000);
await this.scaleImage.ScaleYTo(0, 2000);

Note: We can also scale horizontally, vertically, and relatively using the ScaleXTo, SacleYTo, and RelScaleTo APIs, respectively.

Translate

We can translate a view to another location with an animation. Refer to the following code example.

// Translate to right
await this.translateImage.TranslateTo(50, 0, 1000);

// Translate to bottom
await this.translateImage.TranslateTo(0, 50, 1000);

// Translate to left
await this.translateImage.TranslateTo(-50, 0, 1000);

// Translate to top
await this.translateImage.TranslateTo(0, -50, 1000);

// Diagonal translation
await this.translateImage.TranslateTo(50, 50, 1000);

Note: You can also create these animations with easing functions.

Lottie animation

Lottie animations are free, open-source packages that can be used in your .NET MAUI apps. They animate elements using a JSON file that contains the content for the animation. There are a lot of options available in Lottie animation.

Follow these steps to add Lottie animation to a .NET MAUI application.

Step 1: First, create a .NET MAUI application.

Step 2: Right-click on the project and select Manage NuGet Packages. Browse for SkiaSharp.Extended.UI.Maui and install the package.

Step 3: Then, open the MauiProgram.cs file and configure the SkiaShap like in the following code.

using SkiaSharp.Views.Maui.Controls.Hosting;
builder.UseSkiaSharp();

Step 4: Go to the MainPage.xaml and add the SkiaSharp namespace. Refer to the following code.

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:skia="clr-namespace:SkiaSharp.Extended.UI.Controls;assembly=SkiaSharp.Extended.UI"
             x:Class="MAUIAnimations.MainPage">

Step 5: Finally, add SkLottieView with the options RepeatCount, Repeat Mode, and Source.

Note: Refer to the LottieFiles for a list of JSON files that can be used to add animation to your app. After preparing the JSON file, add it to Resource-> Raw Folder.

Refer to the following code example.

<skia:SKLottieView RepeatCount="-1"
                   RepeatMode="Reverse"
                   Source="example.json"
                   WidthRequest="300"
                   HeightRequest="300"/>
