put fab button in disabled state on the page
Chrome 50, Edge 14
Disabled grayed floating button
button is invisible.
You have the button designated as dark, which means that when disabled it should have a 12% #FFF color as designated here https://material.io/guidelines/components/buttons.html#buttons-raised-buttons.
My suggestion would be to add the class "white--text" and remove the dark prop designation.
Disabled fab button with "white--text" looks bad.
I use this solve it:
<v-btn fab class="indigo" :disabled="disabledCondition">
<v-icon :class="[{'white--text': !disabledCondition }]">delete</v-icon>
</v-btn>
