presentNudge function

Future<void> presentNudge({ required BuildContext context, required NudgeConfig config, EngageActionContext actionContext = EngageActionContext.unknown, VariableScope scope = VariableScope.empty, })

Presents a NudgeConfig over the app, choosing the bottom-sheet or dialog strategy by its surface. Returns a future that completes when the nudge is dismissed (button action, close affordance, scrim, or drag-down).

Implementation

Future<void> presentNudge({
  required BuildContext context,
  required NudgeConfig config,
  EngageActionContext actionContext = EngageActionContext.unknown,
  VariableScope scope = VariableScope.empty,
}) {
  final presentation =
      _presentations[config.surface.displayType] ?? const BottomSheetPresentation();

  // Wrap the content so button taps can hand the host the campaign context, and
  // so the renderers can interpolate `{{ placeholder }}` copy against [scope].
  return presentation.present(
    context: context,
    surface: config.surface,
    content: EngageActionContextScope(
      actionContext: actionContext,
      child: VariableScopeProvider(
        scope: scope,
        child: NudgeView(content: config.content),
      ),
    ),
  );
