Map with different data type, variable does not exist

Question

I am having trouble Saving data through Apex I send to Apex a dict that have different Data type such as {"id": 12345, "field_name":44}

now what I would like to do is

1. send this data to Apex
2. Get the specific lead via the Id
3. update the fields

@AuraEnabled
public static void UW_SavedData(Map<String, Object> record){
    if(record != null){
        string currentId = record.id;
        Lead CurrentProp = [SELECT Id FROM Lead WHERE Id = :record.id];          
        }
    }

My apex look the following ..

my issue is that for :record.id I get the error Variable does not exist: id

Could you explain me what I am doing wrong ?

edited Code:

@AuraEnabled
public static void UW_SavedData(Lead record){
    if(record != null){
        Id currentId = record.get('Id');
        Lead CurrentProp = [SELECT Id FROM Lead WHERE Id = :currentId];          
        }
    }

Answer 1

As a map, you'd have to write:

Id currentId = (Id)record.get('Id'); 

Note that this is case sensitive. You might want to just pass in a record directly:

public static void UW_SavedData(Lead record){

This saves you the trouble of using Maps in Apex.

Answer 2

Unlike JavaScript, to get the value from a key value pair i.e., a map in Apex, you will have to use the get method. For example:

record.get('Id')
