I would like to add a subtask automatically when I add a flag on a issue.

We had the plugin ScriptRunner.

* I used scriptrunner to create a new listener
* Choose the option to create a sub-task from the listener templates
* Select "Issue Updated" as the event
* Enter the below code for the "Condition":

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import com.atlassian.jira.issue.ModifiedValue
import com.atlassian.jira.issue.util.DefaultIssueChangeHolder

def change = event?.getChangeLog()?.getRelated("ChildChangeItem").find {it.field == "Flagged"}
if (change && ('Impediment' in cfValues['Flagged']*.value)){
return true;
}

I was able to get this working in Jira Data Center 7.13

I am not sure this is possible - if adding a flag fires an event, then you can write a listener to catch the event and create a subtask, but I have a feeling no event is fired by flagging or un-flagging.
