Primary entry point exports Structures -  AnimateChildOptions The "AnimateChildOptions" interface is an extension of the AnimationOptions interface and aims to add duration options to control the styling and timing of animations for a specific child element. Let's analyze each part of the provided code to understand its functionality. Interface Extension: AnimateChildOptions extends the AnimationOptions interface. This means that AnimateChildOptions inherits all properties from the AnimationOptions interface and adds new properties specific to controlling animations for child elements. Properties of the AnimateChildOptions Interface:     -  duration?: number | string: This property allows specifying the duration of the animation for the child element. The duration can be provided as a number (representing milliseconds) or as a string with a time unit, such as "2s" for 2 seconds. Inherited Properties from the AnimationOptions Interface:     -  dela

Primary entry point exports Functions  - useAnimation The "useAnimation" function is part of the Angular Animation API and is used to initiate a reusable animation created using the animation() function. Here is a detailed explanation of the parameters and the function's operation:      useAnimation (animation: AnimationReferenceMetadata , options: AnimationOptions = null ): AnimationAnimateRefMetadata Parameters:      animation (AnimationReferenceMetadata):          -  The reusable animation to be initiated. This animation is previously created using the animation() function.      options (AnimationOptions):          -  An options object that may contain a delay value for the start of the animation and additional override values for developer-defined parameters.          -  This parameter is optional, with the default value being null . Returns:      AnimationAnimateRefMetadata:          -  An object containing the animation parameters. Usage Details:      Initia

Primary entry point exports Functions  -  trigger The "trigger" function in the Angular Animation API is used to create a named animation trigger . This trigger contains a list of state() and transition() entries that are evaluated when the expression bound to the trigger changes. The function returns an object encapsulating the trigger data. Here's a detailed breakdown of the trigger function and its usage:      trigger ( name: string, definitions: AnimationMetadata []) : AnimationTriggerMetadata Parameters:      name (string):          - An identifying string for the animation trigger .      definitions (AnimationMetadata[]):          -  An animation definition object containing an array of state() and transition() declarations. Returns:      AnimationTriggerMetadata:          -  An object that encapsulates the trigger data. Usage Notes:      Define in Component Metadata:          -  Define an animation trigger in the animations section of "@Component

Primary entry point exports Functions  - transition The "transition" function in Angular Animation API is used to declare an animation transition that plays when a specified condition is met. This function allows you to define when a transition should occur based on a state change expression. The transition comprises one or more animation steps, and it can be configured with options such as a delay. Here is a detailed breakdown of the transition function and its parameters: Parameters:      stateChangeExpr (string | ((fromState: string, toState: string, element?: any, params?: { [key: string]: any; }) => boolean)):          -  A string with a specific syntax or a function that specifies when the animation transition should occur.          -  The State Change Expression can be:               -  A string with a specific syntax, e.g. , 'open => closed' .               -  A function that compares the previous and current state and returns " true"

Primary entry point exports Functions  -  style The "style" function in Angular Animation API is used to declare a key/value object containing CSS properties and styles. This object can then be utilized for defining an animation state, within an animation sequence, or as styling data for calls to animate() and keyframes() functions. This function provides flexibility in associating styles with animation states, and it supports various forms of input for defining CSS styles. Here is a detailed breakdown of the style function and its parameters: Parameters:      tokens ("*" | { [key: string]: string | number; } | ("*" | { [key: string]: string | number; })[]"):          - A set of CSS styles or HTML styles associated with an animation state.                    -  The value can be any of the following:               - A key-value style pair associating a CSS property with a value.               - An array of key-value style pairs.     

Primary entry point exports Functions - state The "state" function is part of the Angular Animation API and is used to declare an animation state within a trigger that is attached to an HTML element. This function allows you to define named states and associate them with specific styles. These states can then be used in conjunction with the "trigger" and "transition" functions to create animations in Angular applications. Here is a detailed breakdown of the "state" function and its parameters: Parameters:      name (string):          -  One or more names for the defined state , provided as a comma-separated string.                    -  Reserved state names can be used to define styles for specific use cases.                            - void: Used for styling when the element is detached from the application ( e.g. , when an ngIf evaluates to false).               -  * (asterisk): Indicates the default state . Styles associated w

Primary entry point exports Functions  -  stagger The "stagger" function in Angular animations is used within an animation query() call to introduce a timing gap after each queried item is animated. This is particularly useful when you want to create a stagger effect, where each item in a sequence starts its animation with a delay relative to the previous item. Stagger Function: The "stagger" function in Angular introduces a delay after each queried item's animation within an animation query() . It takes two parameters:     -  'timings': A delay value (string or number) that represents the timing gap.     - ' animation': One or more animation steps represented by AnimationMetadata or an array of AnimationMetadata . It returns an object of type AnimationStaggerMetadata that encapsulates the stagger data. Usage in Animation Trigger: In the animation trigger named 'listAnimation' , there is a transition defined for any change
