How do I use a dash at the end of speech to signify an abrupt change of subject? I understand that when using an em dash, there is no space before or after the dash:

“Aren’t the flowers beautiful?” said Wendy.
But what happens when the style guide uses en dashes with spaces around them rather than em dashes? For example, the Guardian Style Guide: https://www.theguardian.com/guardian-observer-style-guide-d
I feel the en dash should be preceded but not followed by a space, as in the following example, but I haven't been able to find anything to confirm that feeling.

“Aren’t the flowers beautiful?” said Wendy.
