impl<T> Default for Builder<T>

where T: Default + Clone,

fn default() -> Builder<T>

Returns the “default value” for a type.

impl LottieBuilderExt for Builder<Lottie>

fn asset(&self, name: &str) -> &Self

Creates a widget that displays an LottieComposition obtained from an AssetBundle.

fn file(&self, file: File) -> &Self

Creates a widget that displays an LottieComposition obtained from a File.

fn memory(&self, byf: Bytes) -> &Self

Creates a widget that displays an LottieComposition obtained from a Uint8List.

fn network(&self, url: &str) -> &Self

Creates a widget that displays an LottieComposition obtained from the network.

fn framerate(&self, framerate: FrameRate) -> &Self

The number of frames per second to render. Use FrameRate.composition to use the original frame rate of the Lottie composition (default) Use FrameRate.max to advance the animation progression at every frame.

fn animate(&self, animate: bool) -> &Self

If no controller is specified, this value indicate whether or not the Lottie animation should be played automatically (default to true). If there is an animation controller specified, this property has no effect.

fn repeat(&self, repeat: bool) -> &Self

Specify that the automatic animation should repeat in a loop (default to true). The property has no effect if animate is false or controller is not null.

fn reverse(&self, reverse: bool) -> &Self

Specify that the automatic animation should repeat in a loop in a “reverse” mode (go from start to end and then continuously from end to start). It default to false. The property has no effect if animate is false, repeat is false or controller is not null.

fn delegates(&self, delegates: LottieDelegates) -> &Self

A group of callbacks to further customize the lottie animation.

fn options(&self, options: LottieDelegates) -> &Self

Some options to enable/disable some feature of Lottie

fn onloaded(&self, f: &str) -> &Self

fn image_provider_factory(&self, factory: LottieImageProviderFactory) -> &Self

fn key(&self, key: &str) -> &Self

fn framebuilder(&self, bundle: LottieFrameBuilder) -> &Self

fn width(&self, width: f64) -> &Self

If non-null, requires the composition to have this width.

fn height(&self, height: f64) -> &Self

If non-null, require the composition to have this height.

fn package(&self, package: &str) -> &Self

fn add_repaint_boundary(&self, value: bool) -> &Self

Indicate to automatically add a RepaintBoundary widget around the animation. This allows to optimize the app performance by isolating the animation in its own Layer.
