Presentum - Declarative presentation engine for Flutter

​
Build dynamic UI at scale

Presentum is a declarative Flutter engine that helps you manage campaigns, app updates, special offers, tips, and notifications with clean, testable, type-safe code. Show the right message to the right user at the right time, with impression limits, cooldowns, A/B testing, and analytics - all handled automatically.

Declarative by design

Describe presentations as data. No imperative show/hide logic.

Type-safe

Generics ensure compile-time correctness. No runtime surprises.

Clean architecture

Business logic in guards, UI in outlets, tracking in storage.

Production ready

Eligibility rules, A/B tests, cooldowns, impression tracking built-in.

​
Quick example

// 1. Define surfaces
enum AppSurface with PresentumSurface {
  homeTopBanner,
  popup;
}

// 2. Create payload
class CampaignPayload extends PresentumPayload<AppSurface, CampaignVariant> {
  final String id;
  final int priority;
  final Map<String, Object?> metadata;
  final List<PresentumOption> options;
}

// 3. Initialize
final presentum = Presentum(
  storage: MyStorage(),
  guards: [CampaignGuard()],
);

// 4. Render
PresentumOutlet(
  surface: AppSurface.homeTopBanner,
  builder: (context, item) => BannerWidget(item),
)
That’s it! Presentum handles eligibility, impressions, cooldowns, and state automatically.
