Component API

Based on lottie-react-native project, under the Apache License 2.0.

Prop	Description	Default	Platform
source	Mandatory - The source of animation. Can be referenced as a local asset by a string, or remotely with an object with a uri property, or it can be an actual JS object of an animation, obtained (for example) with something like require('../path/to/animation.json')	None	All
progress	A number between 0 and 1, or an Animated number between 0 and 1. This number represents the normalized progress of the animation. If you update this prop, the animation will correspondingly update to the frame at that progress value. This prop is not required if you are using the imperative API.	0	All
speed	The speed the animation will progress. Sending a negative value will reverse the animation	1	All
duration	The duration of the animation in ms. Takes precedence over speed when set. This only works when source is an actual JS object of an animation.	undefined	RN
loop	A boolean flag indicating whether or not the animation should loop.	true	All
autoPlay	A boolean flag indicating whether or not the animation should start automatically when mounted. This only affects the imperative API.	false	All
autoSize	A boolean flag indicating whether or not the animation should size itself automatically according to the width in the animation's JSON. This only works when source is an actual JS object of an animation.	false	RN
resizeMode	Determines how to resize the animated view when the frame doesn't match the raw image dimensions. Supports cover, contain and center.	contain	RN
style	Style attributes for the view, as expected in a standard View, aside from border styling	None	All
imageAssetsFolder	Needed for Android to work properly with assets, iOS will ignore it.	None	Android
onAnimationFinish	A callback function which will be called when animation is finished. This callback is called with a boolean isCancelled argument, indicating if the animation actually completed playing, or if it was cancelled, for instance by calling play() or reset() while is was still playing. Note that this callback will be called only when loop is set to false.	None	All
renderMode	Only Android, a String flag to set whether or not to render with HARDWARE or SOFTWARE acceleration	AUTOMATIC	Android
cacheComposition	Only Android, a boolean flag indicating whether or not the animation should do caching.	true	Android
colorFilters	An array of objects denoting layers by KeyPath and a new color filter value (as hex string).	[]	RN
textFiltersAndroid	Only Android, an array of objects denoting text values to find and replace.	[]	Android
textFiltersIOS	Only iOS, an array of objects denoting text layers by KeyPath and a new string value.	[]	iOS

Methods (Imperative API):

Based on lottie-react-native project, under the Apache License 2.0.

Method	Description
play	Play the animation all the way through, at the speed specified as a prop. It can also play a section of the animation when called as play(startFrame, endFrame).
reset	Reset the animation back to 0 progress.
pause	Pauses the animation.
resume	Resumes the paused animation.
init	Init the animation. Required for miniprogram
