Should I handle PaymentIntent.status returned from confirmPayment?

[nzkn]

I am adding card payment in an app:

var intent = await Stripe.instance.confirmPayment(
        paymentIntentClientSecret: clientSecret,
        data: paymentMethodParams,
      );
      if (intent.status == PaymentIntentsStatus.RequiresAction) {
        // Should I add extra handling for any status returned?
      }

I wonder, do I need to handle any intent statuses if the status != PaymentIntentsStatus.Successs?
From what I see on the source code I need to call handleNextAction if the status == PaymentIntentsStatus.RequiresAction, but it is not described in the documentation and I am not sure how other statuses should be handled. Can you provide some examples or references to where this is described?
