```
- getProducts
```
 final StateFlow<List<Product>> getProducts()
```
- getSubscriptions
```
 final StateFlow<List<ProductSubscription>> getSubscriptions()
```
- getAvailablePurchases
```
 final StateFlow<List<Purchase>> getAvailablePurchases()
```
- getCurrentPurchase
```
 final StateFlow<Purchase> getCurrentPurchase()
```
- getStatus
```
 final StateFlow<IapStatus> getStatus()
```
- getInitConnection
```
 final SuspendFunction1<InitConnectionConfig, Boolean> getInitConnection()
```
  Initialize the store connection. Must be called before any other IAP API.
- getEndConnection
```
 final SuspendFunction0<Boolean> getEndConnection()
```
  Close the store connection and release resources.
- getFetchProducts
```
 final SuspendFunction1<ProductRequest, FetchProductsResult> getFetchProducts()
```
  Retrieve products or subscriptions from Google Play by SKU.
- getGetAvailablePurchases
```
 final SuspendFunction1<PurchaseOptions, List<Purchase>> getGetAvailablePurchases()
```
  List the owned/available purchases held by Play Billing — non-consumables, active subscriptions, and any pending transactions returned by BillingClient.queryPurchasesAsync for INAPP + SUBS. Use this to restore purchases or to recover anything not finished previously. (iOS uses Transaction.unfinished / Transaction.all semantics; on Android the concept is "owned by the user", not strictly "unfinished".)
- getRequestPurchase
```
 final SuspendFunction1<RequestPurchaseProps, RequestPurchaseResult> getRequestPurchase()
```
  Initiate a purchase flow. The result is delivered via the purchase update listener, NOT through the return value.
- getFinishTransaction
```
 final SuspendFunction2<Purchase, Boolean, Unit> getFinishTransaction()
```
  Complete a purchase transaction. Call after server-side verification.
- setActivity
```
 final Unit setActivity(Activity activity)
```
- clear
```
 final Unit clear()
```
  Clear listeners and transient state. Call when the screen is disposed.
- initConnection
```
 final Boolean initConnection()
```
  Initialize the store connection. Must be called before any other IAP API.
  Convenience overload — calls the config-accepting variant with null.
- getActiveSubscriptions
```
 final List<ActiveSubscription> getActiveSubscriptions(List<String> subscriptionIds)
```
  Get details of all currently active subscriptions.
- hasActiveSubscriptions
```
 final Boolean hasActiveSubscriptions(List<String> subscriptionIds)

```
 final Boolean launchExternalLink(Activity activity, LaunchExternalLinkParamsAndroid params)
```
  Launch an external content/offer link from inside the Billing Programs flow (Play Billing 8.2.0+).

```
 final Boolean openRedeemOfferCode(Activity activity)
```
  Open the Google Play offer/promo code redemption page (https://play.google.com/redeem) so the user can enter a code. A listener can receive the redeemed purchase while the app has an active billing connection; reconcile available purchases when the app resumes. Does not require the billing client to be initialized.
- getBillingChoiceInfo
```
 final BillingChoiceInfoAndroid getBillingChoiceInfo(GetBillingChoiceInfoParamsAndroid params)
```
  Fetch Billing Choice display assets for developer-rendered choice screens (Play Billing 9.1.0+).

 final BillingResultAndroid showBillingProgramInformationDialog(Activity activity, BillingProgramInformationDialogParamsAndroid params)
```
  Show the mandatory information dialog before a developer-rendered, in-app Billing Choice screen (Play Billing 9.1.0+).

```
 final InAppMessageResultAndroid showInAppMessages(Activity activity, InAppMessageParamsAndroid params)
```
  Show Play billing in-app messages such as payment issues or price-change confirmations.
- enableBillingProgram
```
 final Unit enableBillingProgram(BillingProgramAndroid program)
```
  Enable a billing program for the next connection (8.2.0+; Billing Choice 9.1.0+). This should be called BEFORE initConnection to configure the BillingClient.
  
  Parameters:
  
  program - The billing program to enable
- addPurchaseUpdateListener
