DotLottieController Class (for Composable)

The DotLottieController class provides a comprehensive interface for managing the playback and configuration of dotLottie animations within Jetpack Compose. This reference outlines its properties, methods, and the mechanism for event handling.

Properties

Property	Description	Type	Access
`isPlaying`	Checks if the animation is playing.	`Boolean`	Read
`isLoaded`	Determines if the animation has been loaded successfully.	`Boolean`	Read
`isComplete`	Checks if the animation has completed playing.	`Boolean`	Read
`isStopped`	Indicates whether the animation is stopped.	`Boolean`	Read
`isPaused`	Indicates whether the animation is paused.	`Boolean`	Read
`speed`	The playback speed of the animation.	`Float`	Read
`loop`	Determines whether the animation should loop.	`Boolean`	Read
`autoplay`	Determines if the animation will start playing automatically.	`Boolean`	Read
`totalFrames`	The total number of frames in the animation.	`Float`	Read
`currentFrame`	The current frame of the animation.	`Float`	Read
`playMode`	The play mode of the animation (e.g., forward, reverse).	`Mode`	Read
`segment`	The start and end frames of the current segment being played.	`Pair<Float, Float>?`	Read
`duration`	The duration of the animation in seconds.	`Float`	Read
`loopCount`	The number of times the animation will loop.	`UInt`	Read
`useFrameInterpolation`	Checks if frame interpolation is enabled for smoother animation.	`Boolean`	Read

Methods

Method	Description
`play()`	Starts or resumes the animation.
`pause()`	Pauses the animation.
`stop()`	Stops the animation and resets to the beginning.
`setPlayerInstance(player: DotLottiePlayer)`	Sets the DotLottiePlayer instance to be controlled.
`resize(width: UInt, height: UInt)`	Resizes the animation view.
`setFrame(frame: Float)`	Sets the current frame of the animation.
`setUseFrameInterpolation(enable: Boolean)`	Enables or disables frame interpolation.
`setSegment(firstFrame: Float, lastFrame: Float)`	Defines the start and end frames for a segment of the animation to play.
`setLoop(loop: Boolean)`	Sets whether the animation should loop.
`freeze()`	Freezes the animation at the current frame.
`unFreeze()`	Unfreezes the animation, allowing it to continue.
`setSpeed(speed: Float)`	Sets the playback speed of the animation.
`setPlayMode(mode: Mode)`	Sets the play mode of the animation.
`addEventListener(listener: DotLottieEventListener)`	Adds an event listener to receive animation events.
`removeEventListener(listener: DotLottieEventListener)`	Removes an event listener.
`loadStateMachine(stateMachineId: String): Boolean`	Loads a specific state machine.
`startStateMachine(): Boolean`	Starts the state machine.
`stopStateMachine(): Boolean`	Stops the state machine.
`postEvent(event: Event): Boolean`	Triggers state machine events.
`addStateMachineEventListener(listener: StateMachineEventListener)`	Adds a listener for state machine transition events.
`removeStateMachineEventListener(listener: StateMachineEventListener)`	Removes a state machine transition event listener.
`loadAnimation(animationId: String)`	Loads an animation by its ID.
`loadTheme(themeId: String)`	Loads a theme by its ID.
`manifest(): Manifest?`	Retrieves the dotLottie manifest.

Event Handling

The DotLottieController class allows for the registration of event listeners that implement the DotLottieEventListener interface. These listeners can respond to various animation events, including:

onFrame(frameNo: Float)
onPause()
onStop()
onPlay()
onComplete()
etc…

This API reference provides a detailed overview of the DotLottieController class, enabling developers to fully leverage its capabilities for controlling dotLottie animations within their Jetpack Compose applications.
