Simple Flutter v2ray VPN

I want to develop an application using Flutter that I can connect to v2ray server. like v2rayNG.
Its design doesn’t matter, it just has a simple screen with a connect button. The config related to the connection must be in the background of the program and does not need to be imported by the user. The user only sees the connection button. Actually, I want the code to connect to the v2ray server in Dart language
