CSS

Recommended CSS styles.

.fab-button {
  height: 70;
  width: 70; /// this is required on iOS - Android does not require width so you might need to adjust styles
  margin: 15;
  background-color: #ff4081;
  horizontal-align: right;
  vertical-align: bottom;
}

Use Icon Fonts

First you need to setup icon fonts as described in NativeScript documentation.

After this, you can use icon fonts on FAB by specifiying the unicode as text and add the fas/far class:

<FAB:fab text="&#xf02a;" class="fab-button fas" />
