state

function

Declares an animation state within a trigger attached to an element.

  
    state(  name: string,  styles: AnimationStyleMetadata,  options?: { params: { [name: string]: any; }; }): AnimationStateMetadata;

Use the trigger() function to register states to an animation trigger. Use the transition() function to animate between states. When a state is active within a component, its associated styles persist on the element, even when the animation ends.

AnimationStateMetadata

Declares an animation state within a trigger attached to an element.

@paramnamestring

One or more names for the defined state in a comma-separated string. The following reserved state names can be supplied to define a style for specific use cases:

void You can associate styles with this name to be used when the element is detached from the application. For example, when an ngIf evaluates to false, the state of the associated element is void.
* (asterisk) Indicates the default state. You can associate styles with this name to be used as the fallback when the state that is being animated is not declared within the trigger.

@paramstylesAnimationStyleMetadata

A set of CSS styles associated with this state, created using the style() function. This set of styles persists on the element once the state has been reached.

@paramoptions{ params: { [name: string]: any; }; }

Parameters that can be passed to the state when it is invoked. 0 or more key-value pairs.
