approve method
Approve a Comment or Submission.
Approving a comment or submission reverts removal, resets the report
counter, adds a green check mark which is visible to other moderators
on the site, and sets the approvedBy
property to the authenticated
user.
Implementation
Future<void> approve() async => content.reddit.post(
apiPath['approve'], <String, String>{'id': content.fullname!},
discardResponse: true);
