unpinChatMessage method
Use this method to remove a message from the list of pinned messages in a chat
If the chat is not a private chat, the bot must be an administrator in the chat for this to work and must have the 'can_pin_messages' admin right in a supergroup or 'can_edit_messages' admin right in a channel.
Returns True on success.
If message_id
not specified, the most recent pinned message (by sending date) will be unpinned.
Implementation
Future<bool> unpinChatMessage(dynamic chat_id, {int? message_id}) async {
if (chat_id is! String && chat_id is! int) {
return Future.error(TelegramException(
'Attribute \'chat_id\' can only be either type of String or int'));
}
var requestUrl = _apiUri('unpinChatMessage');
var body = <String, dynamic>{'chat_id': chat_id, 'message_id': message_id};
return await HttpClient.httpPost(requestUrl, body: body);
