any update about this issue

[RAJ-BODA]

i have checked this issue deeper there is mistake in plugin file android/src/main/kotlin/com/phonepe/phonepe_payment_sdk/PhonePePaymentSdk.kt: line 113

if (resultCode != Activity.RESULT_CANCELED) is wrong condition because it should be something like this if (resultCode == Activity.RESULT_SUCCESS)

/**
     * This method gets called everytime from the app who has opened intent using startActivityOnResult()
     * Return true, If B2B_PG (725) & Container (101) which are phonepe payment request codes, we will be doing response handling.
     * Return false, if some other request code comes as it's not phonepe related code.
     */
    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?): Boolean {
        logInfo("onActivityResult: requestCode:$requestCode resultCode:$resultCode, data: ${data.convertResultToString()}")
        return try {
            if (requestCode == B2B_PG || requestCode == CONTAINER) {
                if (resultCode != Activity.RESULT_CANCELED)
                    result.success(hashMapOf(STATUS to GlobalConstants.Response.SUCCESS))
                else
                    result.success(hashMapOf(STATUS to FAILURE, ERROR to data.convertResultToString()))
                true
            } else
                false
        } catch (ex: Exception) {
            logInfo("Exception: ${ex.localizedMessage}")
            false
        }
    }
