Examples

Example 1: Simple lottieImage layer

Show ExampleHide Example

Lottie animations use a JSON-based file format.

{
  "type": "lottieImage",
  "value": "asset://icon-rocket.json",
  "classes": [
    "fullSize"
  ]
}

Example 2: LottieImage layer without autoplay

Show ExampleHide Example

Since autoplay is disabled, the animation must be started using a layer action.

{
  "type": "lottieImage",
  "name": "lottieImage02",
  "value": "https://samples.mobilitysuite.de/animation.json",
  "repeating": false,
  "autoplay": false,
  "actions": [
    {
      "type": "layerAction",
      "params": {
        "layerName": "lottieImage02",
        "actions": [
          {
            "type": "play",
            "params": {
              "async": false
            }
          }
        ]
      }
    }
  ]
}

Just like regular images, Lottie animations can also be hosted on a web server instead of using a local asset.
