Triggers

Triggers let you perform Actions in your app, such as when interactive components like pressable, swipeable, or input components, are engaged by the user. Or when a Screen loads.

For example, a Button component has multiple Triggers, including the most obvious one - On Press. Using a Button’s On Press Trigger, you can configure any of the available Actions to run when that Button is pressed.

If a component has any Triggers, they will be listed in the Interactions tab in the right panel of the Builder. The Triggers that are available will depend on the type of component you want to run Actions with. For example, our Button doesn’t have an On Swiped Right Trigger, but our Deck Swiper component does.

Caution

Below is a list of some common Triggers, but it’s not complete. Refer to the docs or Interactions tab for a specific component to see which Triggers are available to it.
