I encountered a NullPointerException when attempting to invoke the isValidVpa method in the Razorpay Flutter plugin. The error occurs when the method is called, resulting in the following stack trace:

@SelvaKumar92 You will need to trigger initilizeSdk("{razorpay_api_key}") function before calling isValidVpa().
