与多个文件一起打包，如何结构

Question

Go noob, I cannot seem to figure out how to structure my project with packages. What I want is this:

• I want to create a package, lets say its called Dart.
• I have a file called dart.go with package main and the main function in my project directory.
• I have another file, lets call it functions.go in my project directory with 'package dart' as the first line.
• I just want to call functions from functions.go in main, but cannot figure out how to name the packages to get it to build.
• If I put package dart at the top of functions.go it wont build because it finds packages main and dart. I dont want functions.go to be part of another package, I just want one package and the ability to split the functions in this package into multiple files.
• Is this possible in go, or do I have to make multiple packages?

dart.go

package main 

import (
  ...
)  

func main () {
  ...
  // call functions declared in functions.go
  ...
}

functions.go

package dart  

import (
  ...
)

func Function1() {
  ... 
}

func Function2() {
  ...
}

Answer 1

if all you want to do is access functions in a different file, have functions.go also start with package main instead of package dart. That way, you are working within a single package but with your code divided into multiple files. Make sure they're in the same directory so that they're considered in the same package.
