Golang loop until key pressed

I'm using Go and I need to be able to run a loop until a certain key is pressed. Are there any libraries or is there any functionality that allows this to happen? I just need to detect if a key is down on each iteration of the loop. I've tried using azul3d, but it wasn't quite what I was looking for...

This is what I'm hoping for:

exit := false
for !exit {
    exit = watcher.Down(keyboard.Space)
}

or something similar

I believe you can use this fmt.Scanln() instead

Use keyboard with its termbox backend, like this:

package main

import "github.com/julienroland/keyboard-termbox"
import "fmt"
import term "github.com/nsf/termbox-go"

func main() {
    running := true
    err := term.Init()
    if err != nil {
        panic(err)
    }

    defer term.Close()

    kb := termbox.New()
    kb.Bind(func() {
        fmt.Println("pressed space!")
        running = false
    }, "space")

    for running {
        kb.Poll(term.PollEvent())
    }

}
