how to change the tigger widget

[davigmacode]

To change the trigger widget, you can use the anchorBuilder property. This property takes a builder function that creates the widget that will be used as the trigger.

PromptedChoice(
  ...,
  anchorBuilder: (state, openPrompt) {
    return YourTriggerWidget(
      onTap: openPrompt,
    );
  },
)

Also, you can use the customizable default trigger builder

PromptedChoice(
  ...,
  anchorBuilder: ChoiceAnchor.create(valueTruncate: 1),
)
