Easiest Integration of Subscriptions in Flutter

We love Flutter and we offer Flutter plugins to integrate your subscriptions into your Flutter app as easily as possible, including a customizable paywall.

Subscriptions for Flutter are ready with just 4 lines of code.

How to add Subscriptions

1. Initialize LinkFive

// Get your API key after sign up. Docs
LinkFivePurchases.init("LinkFive Api Key");

2. Get all products

// Subscriptions to offer to the user. Docs 

// Active subscriptions the user purchased. Docs

3. Purchase the product

// This handles the entire purchase process. Docs

4. Enable Premium Content

// That's it
// It's time to show your premium content


User Management included

All your users appear in the LinkFive user overview. If your users then decide to buy a subscription in your Flutter app, this is displayed in detail.

You can also manually assign your users a premium plan for a certain period of time. Your users can even own and benefit from the same plan on multiple platforms.

  • Multi platform subscription plans
  • Enable team subscriptions
  • Family subscription plans are even possible

Flutter Subscriptions Plugin Features

Dynamic subscription offer

Our plugin will provide your app with the subscriptions you want to offer to your users. You can change your subscription offer in our UI and our plugin will update your app. A single method .fetchSubscriptions() is enough and you can offer your subscription.

Make a purchase

Our Flutter plugin takes care of everything related to a purchase. All you need to do is call .purchase( ... ) and we will do everything else for you.

Subscription receipt validation

Our Flutter plugin checks if a purchase is genuine and not fake.

Get active subscriptions

If your user has purchased your subscriptions, our plugin streams all the important information your app needs to activate your user's premium status.

Seamless integration with our paywall UI plugin

Integrating our Flutter UI plugin into your app is seamless and effortless.
The plugin works immediately together with our purchase plugin.
Only one line of code is required to display your subscriptions.

callbackInterface: linkFivePurchases,
// ...

That's it. The subscriptions are now ready for sale!

Managing the Purchase State

The plugin can also manage the UI state of the paywall.

You can always use the same UI page for your subscriptions. We make sure that either the success page is displayed if the user has purchased Premium, or the paywall if the user has not yet purchased.

// no additional code needed
// you can still add comments if you like, tho

Flutter Provider Plugin

We created a Flutter provider plugin to make it even easier to add subscriptions to your app!

Register LinkFiveProvider.

The Provider can be found on pub.dev. The integration can be easily done by adding the LinkFiveProvider to your provider root including your api key.

providers: [
// ...
create: (context) => LinkFiveProvider("API_KEY"),
lazy: false,

The provider is now ready to use and loads all active subscriptions. Your App can access the provider by consuming the provider like any other provider implementation in your app. To get a fully functional paywall, use our paywall plugin and add the provider as a parameter like in the example below.

builder: (_, provider, __) {
return PaywallScaffold(
child: SimplePaywall(
callbackInterface: provider.callbackInterface,
subscriptionListData: provider.paywallUIHelperData(context),
// ...

The plugin also loads, in combination with the SimplePaywall, all available subscriptions that you want to offer if the user has not yet purchased a subscription. If you do not use the SimplePaywall, make sure to call fetchSubscriptions if the user has no active subscriptions.
