I am looking into understanding the flow triggers and want to understand the below pointers:
Like we put common logic in generic/reusable methods in apex, can we do something like this in flows as well? For example, if I have a common roll-up logic say, count of contacts on the account record.
$Record could store one single record. How are we then able to perform bulk record operations in flows?
We cannot perform 'After Delete' and 'Undelete' operations. What could be done in case of above example (roll-up)?
