Placement of multiple .envs

[alexw92]

Suppose I have .env.dev and .env.prod, where would i put them if I want to include only the prod env in a production bundle? The example places the .env file in assets but arent all assets part of build bundle? It would be cool if there was an example for dealing with multiple envs storing all of them in the same location. Maybe it is super obvious, in that case I am sorry to ask
