Friendly wave. Or flirty wave?

I saw the girl I'm into, just an hour ago as I was headed home and she was headed to her class. We were texting before hand but we just wound up seeing each other on the off chance that we passed each other at the same time. She waved like the queen does or like when Miss America does when she's going down the aisle. Hard to explain but I think you get the idea. Was this a friendly wave or a flirty one.

We didn't get to talk in person by the way
