Is it possible to use "Flash channels" to send non-transactional data, A.K.A 'zero-value' transaction type which simply broadcasts a message or data?
If so, is it free? And how to do it?

Why would you want to do this? Why not simply broadcast a message or data without Flash Channels? – Zauz Jun 25 '18 at 10:56

because it is faster – user3785971 Jun 25 '18 at 11:00

No, it's not... Where did you get the impression, that it would be? – Zauz Jun 25 '18 at 11:03

flash channels make transactions faster. https://blog.iota.org/instant-feeless-flash-channels-88572d9a4385 – user3785971 Jun 25 '18 at 11:10

They enable the transacting of Iotas without doing Proof Of Work (doing POW takes a long time). But for sending data over the Internet (or any network), you don't have to do POW. You just send the data. – Zauz Jun 25 '18 at 11:16

i want that this data to be verified into the Tangle. – user3785971 Jun 25 '18 at 11:18

Transactions made in flash channels are not written to the Tangle.
There are only two events that are stored:
- opening of a flash channel
- closing of a flash channel
When opening a flash channel, two (or more) entities, let's call them Alice and Bob, lock up Iotas.
- Alice and Bob open a Flash Channel (while still online)
- Alice and Bob loose connection to any full nodes but are still connected with each other
- now Alice can send IOTAs to Bob and vice versa, POW is not required
- once they reconnect to a full node, they close the channel
This is why it wouldn't make sense to "broadcast a message or data" via Flash Channels. It would be just as good as broadcasting it without flash channels.

Is it possible to store the data that flows from one address to another into a private blockchain/DAG since it is not being stored on the Tangle ? – user3785971 Jun 26 '18 at 17:33

Of course, it's just data. You can do anything you want with it. But you would have to pay fees/do POW (whatever the private blockchain/DAG requires you to do in order to store data). – Zauz Jun 26 '18 at 17:37
