Message drafts in Telegram allow syncing the text typed into message fields between devices.
-Drafts are represented by the DraftMessage constructors. -The parameters of the peer-specific draft should be used as defaults when composing a message to be sent to a certain peer (in the case of media, the same draft should still be used as base, the message will become the caption). -If the user exits the app before sending the message, the message should be saved as a draft:
-Drafts can be saved using the messages.saveDraft method.
-New drafts are automatically sent to all devices via updateDraftMessage updates.
-Dialog objects fetched via the API also contain the draft associated with the dialog.
-Drafts can be cleared by setting the clear_draft flag when sending messages or media using messages.sendMessage, messages.sendMedia, messages.sendMultiMedia, messages.sendInlineBotResult and similar or manually by passing empty values to messages.saveDraft.
