"""Get a user's dialogs sequentially.
.. include:: /_includes/usable-by/users.rst
Parameters:
limit (``int``, *optional*):
Limits the number of dialogs to be retrieved.
By default, no limit is applied and all dialogs are returned.
pinned_only (``bool``, *optional*):
Pass True if you want to get only pinned dialogs.
Defaults to False.
chat_list (``int``, *optional*):
Chat list from which to get the dialogs; Only Main (0) and Archive (1) chat lists are supported. Defaults to (0) Main chat list.
offset_date (:py:obj:`~datetime.datetime`, *optional*):
The date starting from which the dialogs need to be fetched. Use 0 or any date in the future to get results from the last dialog.
offset_message_id (``int``, *optional*):
The message identifier of the last message in the last found dialog, or 0 for the first request.
Returns:
``Generator``: A generator yielding :obj:`~pyrogram.types.Dialog` objects.
Example:
.. code-block:: python
# Iterate through all dialogs
async for dialog in app.get_dialogs():
print(dialog.chat.first_name or dialog.chat.title)
