Animation Flash

Using Angular Animations to Create a "Flash" Animation

Imports:

In Angular, the animations module (@angular/animations) provides a set of functions that facilitate the creation of animations for DOM elements. Here are the imported functions and their purposes:

Here, we're importing the necessary functions from the Angular animations module.

• trigger: This function is used to create a new animation with a specific name.
• style: This function is used to define CSS styles that will be applied during an animation.
• animate: This function is used to define animations that change CSS styles over time.
• transition: This function is used to define transition states between different animation states.

Exporting the flash animation:

Here, we're exporting a constant called flash, which is an animation defined by the trigger with the name 'flash'.

Transition Definition:

This is the transition definition for the :enter state, which is activated when an element is inserted into the DOM. Here, we're defining a series of animations that occur sequentially when an element is inserted.

Animations:

These are the animations that occur sequentially when the :enter state is activated.

• animate: Defines an animation with a duration of 0.5 seconds, using a smooth easing timing function (ease-in-out).
• style({ opacity: X }): Defines the CSS style for the animated element. Here, we're adjusting the opacity of the element to different values (1 and 0) to create a blinking effect.

Therefore, when an element is inserted into the DOM and the flash animation is applied to it, the opacity of the element is adjusted in a sequence of five steps, creating a blinking effect.
