My 7 year old daughter is complaining of flu like symptoms and has a fever of 102. Is that dangerously high?

Influenza, fever. Influenza can often give children high fevers, even 106, for days at times. A fever will not hurt her unless it is very high. Higher than 102. A fever is a sign of her body trying to fight the virus. Use acetaminophen, or ibuprofen, dosed by her weight. Push plenty of an electrolyte solution to keep her hydrated. And please get yearly flu shots if you have not yet.
