I think you're looking for this query:

FirebaseFirestore.instance
  .collection('users')
  .where('category', isEqualTo: 'fashion')
  .get()
  .then(...);

I highly recommend reading the FlutterFire documentation on filtering data , and keeping the reference documentation on the where method handy.
