If I correctly understand your question, you should use a Collection group query and pass the following Stream to the StreamBuilder:

stream: Firestore.instance.collectionGroup('userPosts').where('work', isEqualto: 'something').snapshots();

The userPosts collection group consists of all (sub)collections with the ID userPost. Note that you must create an index that supports your collection group query.
