How do I minimize the size of a Flutter Web Release? Is the NOTICES File required?

My web folder after building my Flutter Web app comes to 5.4MB which isn't too bad, but I might as well optimize.

I was wondering if anybody has any tips outside the obvious(removing unnecessary packages), to minimize the file size? I'll be hosting on Firebase.

Also, there is a NOTICES file which is about 1MB filled with random licenses/copyright disclaimers, are there any consequences to deleting this?

Is flutter build web all you do to build a release version? Is there anything else that should be done other than flutter clean?
