FLS Create for Saleforce Object - salesforce

Question

Is there a way to apply FLS Create check - Schema.sObjectType.Account.fields.Name.isCreateable() to the following?
public static Account createAccount() {
return new Account(
Name = 'Test',
OwnerId = UserInfo.getUserId()
);
}
Wondering if there is a way to apply without re-writing to the following:
public static Account createAccount() {
Account a = new Account();
if (Schema.sObjectType.Account.fields.Name.isCreateable()) {
a.Name = 'Test';
}
if (Schema.sObjectType.Account.fields.OwnerId.isCreateable()) {
a.OwnerId = UserInfo.getUserId();
}
insert a;
}

You can create a generic method that can iterate on each field to check for the FLS.
if access available then retain
if access not available then remove the particular field from the object instance.
I Have created a Generic Method to truncate the non-writable fields as follow:
public static List<SObject> truncateNotWriteableFields(List<SObject> listSObject){
Set<String> readOnlyFields = new Set<String>();
List<SObject> listSObjectNew = new List<SObject>();
if(listSObject.size() < 1){
return listSObjectNew;
}
Schema.SObjectType sObjType = listSObject.getSObjectType();
for(SObjectField field : sObjType.getDescribe().fields.getMap().values()){
if(field.getDescribe().isAccessible() && !field.getDescribe().isUpdateable() && !field.getDescribe().isCreateable()){
readOnlyFields.add(String.valueOf(field));
}
}
readOnlyFields.remove('Id'); // avoid removal in update
for(SObject obj : listSObject){
Map<String, Object> objMap = (Map<String, Object>) JSON.deserializeUntyped( JSON.serialize( obj ) );
objMap.keySet().removeAll(readOnlyFields);
SObject objWithoutNotWritableFields = (SObject) JSON.deserialize( JSON.serialize( objMap ), SObject.class );
system.debug('objWithoutNotWritableFields=>'+objWithoutNotWritableFields);
listSObjectNew.add(objWithoutNotWritableFields);
}
return listSObjectNew;
}
