If you already have material-icons working in your web project, just need to update your reference in the html file and the used class for icons:
html reference:
Before
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet" />
After
<link href="https://fonts.googleapis.com/css?family=Material+Icons|Material+Icons+Outlined|Material+Icons+Two+Tone|Material+Icons+Round|Material+Icons+Sharp"
rel="stylesheet" />
material icons class:
After that just check wich className are you using:
Before:
<i className="material-icons">weekend</i>
After:
<i className="material-icons-outlined">weekend</i>
that works for me... Pura vida!
