// Make a purchase, Adapty handles the rest

	final profile = await Adapty().makePurchase(product: product);
	// successful purchase
} on AdaptyError catch (adaptyError) {
	// handle the error
} catch (error) {
	// handle another errors
}

From integration to maintenance – Adapty is created to make working with IAP easier.
