Package: Lottie

Lottie is the highest-level control in the repository. It loads a Skottie animation, renders it through CompositionAnimatedControl, and exposes helpers that are convenient for UI playback controls.

Install

dotnet add package Lottie

What it gives you

Path for asset or file loading
RepeatCount and PlaybackRate
Play(), Pause(), Resume(), Stop()
Seek(TimeSpan), SeekSeconds(double), SeekProgress(double)
PositionSeconds and DurationSeconds for slider binding

Basic usage

<Lottie Path="/Assets/LottieLogo1.json"
        RepeatCount="-1" />

Interactive usage

<Lottie x:Name="Player"
        Path="{Binding SelectedAsset.Path}"
        RepeatCount="-1" />

<Slider Minimum="0"
        Maximum="{Binding #Player.DurationSeconds}"
        Value="{Binding #Player.PositionSeconds, Mode=TwoWay}" />

This matches the pattern used by the samples/LottieDemo application, which also binds PlaybackRate and exposes play/pause/resume/stop buttons.

Asset loading behavior

The control can load:

relative asset paths such as /Assets/LottieLogo1.json,
avares:// resource URIs,
local files when the path resolves to a file URI.

If the path changes before the control is attached to the visual tree, the control stores it and loads it on Loaded.

When to use it

Use Lottie when you already have Lottie JSON assets and want a finished player surface. If you need to author custom Skia visuals instead of playing existing assets, use CompositionAnimatedControl directly.
