Observerモードでフローを表示する - React Native

React コンポーネントの場合は、AdaptyFlowView の props としてハンドラーを渡します。

function MyFlow({ flow }) {
  const onObserverPurchaseInitiated = useCallback<
    FlowEventHandlers['onObserverPurchaseInitiated']
  >((product, onStartPurchase, onFinishPurchase) => {
    onStartPurchase(); // the flow shows its loading indicator
    myPurchaseApi(product.vendorProductId)
      .then((transactionId) => adapty.reportTransaction(transactionId, flow.variationId))
      .finally(() => onFinishPurchase()); // the flow hides the loading indicator
  }, [flow]);

  const onObserverRestoreInitiated = useCallback<
    FlowEventHandlers['onObserverRestoreInitiated']
  >((onStartRestore, onFinishRestore) => {
    onStartRestore();
    myRestoreApi().finally(() => onFinishRestore());
  }, []);

  return (
    <AdaptyFlowView
      flow={flow}
      onObserverPurchaseInitiated={onObserverPurchaseInitiated}
      onObserverRestoreInitiated={onObserverRestoreInitiated}
      // ... your other event handlers
    />
  );
}

モーダル表示の場合は、作成したビューにハンドラーを設定します。

const view = await createFlowView(flow);

const unsubscribe = view.setEventHandlers({
  onObserverPurchaseInitiated(product, onStartPurchase, onFinishPurchase) {
    onStartPurchase(); // the flow shows its loading indicator
    myPurchaseApi(product.vendorProductId)
      .then((transactionId) => adapty.reportTransaction(transactionId, flow.variationId))
      .finally(() => onFinishPurchase()); // the flow hides the loading indicator
    return false; // keep the flow open; dismiss it yourself after success
  },
  onObserverRestoreInitiated(onStartRestore, onFinishRestore) {
    onStartRestore();
    myRestoreApi().finally(() => onFinishRestore());
    return false;
  },
});
