ShouldEncryptStanzaCallback typedef
A callback for figuring out whether a stanza should be encrypted or not. Note that returning true here does not necessarily mean that a stanza gets encrypted because handlers can indicate that a stanza should not be encrypted, e.g. PubSub.
Implementation
typedef ShouldEncryptStanzaCallback = Future<bool> Function(
JID toJid,
Stanza stanza,
);
