Does anybody know how to use/enable the animated icons in an Angular Web Application which are shown in the material design documentation: https://material.io/design/iconography/animated-icons.html#usage
As other have stated the examples on the Material Icon sites would have to be built.
However, I found my way to this question looking for a guide on how to animate angular material icons and for others looking for the same I have a solution. The default animation can be customized to something other than just a 360 degree rotation.
Basically you can create a component that swaps between mat-icon's when clicked or when a parent element like a button is clicked.
Prerequisites are you have a an angular material application with material icons installed. I used Angular Material 8.
Here is a working Stackblitz https://stackblitz.com/edit/angular-material-prototype-animated-icon
mat-animated-icon.component.ts
import { Component, Input, OnInit } from '@angular/core';
@Component({
selector: 'mat-animated-icon',
templateUrl: './mat-animated-icon.component.html',
styleUrls: ['./mat-animated-icon.component.scss']
})
export class MatAnimatedIconComponent implements OnInit {
@Input() start: String;
@Input() end: String;
@Input() colorStart: String;
@Input() colorEnd: String;
@Input() animate: boolean;
@Input() animateFromParent?: boolean = false;
constructor() { }
ngOnInit() {
console.log(this.colorStart);
console.log(this.colorEnd);
}
toggle() {
if(!this.animateFromParent) this.animate = !this.animate;
}
}
mat-animated-icon.component.scss

font-family: 'Material Icons';

font-style: normal;

&.md-dark {

&.md-inactive { color: rgba(0, 0, 0, 0.26); }
}
/* Rules for using icons as white on a dark background. */
&.md-light {
color: rgba(255, 255, 255, 1);
&.md-inactive { color: rgba(255, 255, 255, 0.3); }
}
.material-icons {
transition: transform .5s;
&.animate {
transform: rotate(360deg);
}
}
}
mat-animated-icon.component.html
<mat-icon [ngClass]="{'animate' : animate}" color="{{animate ? colorEnd : colorStart}}" (click)="toggle()">{{animate ? end : start}}</mat-icon>
var.directive.ts
a little helper directive
import { Directive, Input } from '@angular/core';
@Directive({
selector: '[var]',
exportAs: 'var'
})
export class VarDirective {
@Input() var:any;
constructor() { }
}
Example of the component in use
<button (click)="!this.disabled && iconAnimate10.var=!iconAnimate10.var" #iconAnimate10="var" var="'false'" mat-icon-button [disabled]="false" aria-label="Example icon-button with a heart icon">
<mat-animated-icon start="menu" end="close" colorStart="none" colorEnd="none" [animate]="iconAnimate10.var" animateFromParent="true"></mat-animated-icon>
