I won't go into the "I know her for a while" part
you cannot flirt with someone and not be noticed, and if u are it's pretty useless flirting

You need to demonstrate more value. Maybe flirt with some other girl in the class, so she sees that you have options. When she sees that you are preselected by women, she will be much more attracted to you. It might also be a good idea to let her overhear you talking about how much fun you had doing something with other people. Let those other people talk about it too. Then, a while later, tell her about it. She will probably want to be a part of that stuff, and then you can say that you have another thing planned, and that you will text her with the details. That's how you get her number. After that, make sure there are other women at this thing, so she can still see that you have high value to women.
