NWAction class

What happens when the user taps an NWButton or the widget itself.

increment, decrement, toggle, set and cycle are native actions: the generated widget code changes the stored value and redraws on its own, without starting Dart. Use callback when the reaction needs your Dart code (network, database, ...).

Action	Android	iOS 17+	iOS 14–16
openApp	✅	✅	✅
native	✅	✅ (App Intent)	opens the app, which applies it
callback	✅	✅ (App Intent)	opens the app, which runs it

const

NWAction.cycle(String key, List<String> values)

Moves the field to the next entry of values, wrapping around.

const

NWAction.decrement(String key, {int by = 1, int? min, int? max})
