3. Initiate a purchase or subscribe flow

Initiate a purchase or subscribe flow using the below code:

/// To launch a purchase flow
PurchaseInfo purchaseInfo = await FlutterPoolakey.purchase('your product id (SKU)', payload: '');

/// To launch a subscribe flow
PurchaseInfo purchaseInfo = await FlutterPoolakey.subscribe('your product id (SKU)', payload: '');

productId is your product's identifier (also known as SKU). payload is an optional parameter that you can send, bazaar saves it in the PurchaseInfo. You can access it through your back-end API.

If any error happened (like when the user cancels the flow) it throws a [PlatformException] with a stacktrace. You must handle the error with your logic.

If it succeeded, it returns the PurchaseInfo of the purchased product.
