We built this proof of concept component based on a question posted in the Ionic Forum.
The visual design is based on this blog post from CSS-Tricks.
<unlocker (unlocked)="unlockedHandler($event)"></unlocker>
When the user releases the thumb, the component will emit an unlocked event with a boolean if the slider was slid completly to the end of the track.
For now, the text that is shown in the slider track is set within the unlocker.scss.
