The Angular Material Tree component is not rendering properly in an Angular tutorial demonstration

Upon completing the installation of @angular/material, @angular/cdk, and @angular/animations through npm install --save, I attempted to reconstruct the flat tree example provided by Angular. Unfortunately, even after addressing the error message stating 

Could not find Angular Material core theme
by referencing a solution on Stack Overflow and adding 

@import '../node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css';

to my global styles.scss, the tree still fails to display correctly.

No errors are being reported in the console. Can anyone offer assistance in resolving this issue?

Answer №1

To properly display the icons, it is essential to include the Angular Material Icon Font. To achieve this, simply insert the following line into your index.html file:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

If you require further details, please refer to the official Getting started section within the Angular Material documentation.
