inorganic chemistry - Does fluorine in FNO3 have +1 oxidation number?

According to my textbook and also Wikipedia, fluorine nitrate is a compound which can be created (though it is unstable). Also my textbook says that fluorine has a $+1$ oxidation state. But how is $+1$ state of fluorine possible?

I read in another textbook that fluorine can only show $0$ and $-1$ oxidation states (even Wikipedia says so).

Can someone explain as to how fluorine nitrate exists with a $+1$ oxidation state of fluorine?
