The issue is coming from

https://github.com/Dn-a/flutter_inner_drawer/blob/9dbe02e648dd9db8ec018a0ce4b1ca3839cbc0b3/lib/inner_drawer.dart#L435-L437

children doesn't accept any nullable widget.

Also _trigger(..) method returning nullable widget

https://github.com/Dn-a/flutter_inner_drawer/blob/9dbe02e648dd9db8ec018a0ce4b1ca3839cbc0b3/lib/inner_drawer.dart#L544-L563 And It is being used on https://github.com/Dn-a/flutter_inner_drawer/blob/9dbe02e648dd9db8ec018a0ce4b1ca3839cbc0b3/lib/inner_drawer.dart#L600-L620

While the children can't be null anymore, we can remove or replace _trigger() widget when it returns null.
