This sentence has a handful of deleted comments about the apparent obviousness of her being a girl. With this comment I just want to say that a daughter might well be an adult woman or even an old lady, so it's not as self-evident as one might think.
So in which age does flicka apply? Is a teenager a flicka too or is it only for children?
It usually has the same age range and meaning as the English "girl". And like "girl", it can be applied to just about any age in the right context.
To be fair, a lot of people colloquially generally use "girl" to mean a female or transwoman of whatever age even though the word implies a child. Maybe it's not the same for how the Swedes think of it though.
