Hi Shubham,
May I know how are you going to display the pdf once it is generated on button click?

As a workaround, you can use navigation functionality on lightning component, when clicked set the recordId as a gating paratmeter to the naviurl and use the extension/custom controller's constructor to get the Id of the record from the url parameter.
Navigation would be like this: 
let recordId = component.get("v.recordId");
let urlVar = <VFPageLink>+'/?&rId='+recordId;
        
        var eUrl= $A.get("e.force:navigateToURL");
        eUrl.setParams({
            "url": urlVar
        });
        eUrl.fire();

You can use "navigateToURL" functionality as I have mentioned above

If you are facing issues in fetching Url, plz refer the link (https://salesforce.stackexchange.com/questions/4683/how-to-display-the-browser-current-url-in-visualforce-page)

My js code:

  exportPdf: function(component, event, helper) {
  
    var recordId = component.get("v.recordId");   
        console.log('Recardid',recordId);
    let urlVar = 'https://project--acc.cs18.visual.force.com/apex/demoPdf?core.apexpages.request.devconsole=1'+'/?&rId='+recordId;
        console.log('urlVar',urlVar);
        var eUrl= $A.get("e.force:navigateToURL");
        eUrl.setParams({
            "url": urlVar
        });
        eUrl.fire();
    }

 

My apex code:

 


    public  List<ParentWrap> parentWrapperList {get;set;}
    
    public PP4_PartnerBusinessPlan(ApexPages.StandardController controller){
        String recordId = ApexPages.currentPage().getParameters().get('rId'); 
      Partner_Business_Plan__c abc =(Partner_Business_Plan__c) controller.getRecord();
         system.debug('abc'+abc);
        system.debug('shdsd'+recordId);

And so on...

 

I have doing everything like you say already but  system.debug('shdsd'+recordId); gives null

hi Shubham,
Plz update your navigate Url as below : 
let urlVar = 'https://project--acc.cs18.visual.force.com/apex/demoPdf?'+'rId='+recordId;

Thanks now it's working, the issue is in the controller. Thanks for your help.

Have you any idea how to change the name of pdf opened in new name according to the record name.

I try by using this: Apexpages.currentPage().getHeaders().put('content-disposition', 'attachment; filename='+pp.Name+'.pdf');

but it downloads pdf instead of showing it in new tab.

I faced the same issue, that i was getting the id as null...but here's the mistake that i made:
public PDMS_CRED_PDFGenerator(ApexPages.StandardController controller) {
        currentRecordId  = ApexPages.CurrentPage().getparameters().get('id');
        system.debug('currentRecordId///'+currentRecordId);
    }
instead of:
public PDMS_CRED_PDFGenerator() {
        currentRecordId  = ApexPages.CurrentPage().getparameters().get('id');
        system.debug('currentRecordId///'+currentRecordId);
    }
for your scenario you cannot use 'ApexPages.StandardController controller' as a parameter for constructor, it should not receive any parameter actually, so in short the 2nd way will work.

Thanks,
Namrata
