ModeType() doesnt show permissions and modes on macos

[vireshwali]

go version: go version go1.16.3 darwin/amd64
godirwalk version: github.com/karrick/godirwalk v1.16.1
code used:

godirwalk.Walk(startingDir, &godirwalk.Options{
	Callback: func(osPathname string, de *godirwalk.Dirent) error {
		fmt.Printf("%s %s\n", de.ModeType(), osPathname)
		return nil
	},
	Unsorted:            true,
	FollowSymbolicLinks: false,
})

Observed Output:

d--------- /Library/Caches
---------- /Library/Caches/.DS_Store
d--------- /Library/Caches/ColorSync
---------- /Library/Caches/ColorSync/com.apple.colorsync.devices
d--------- /Library/Caches/com.apple.cloudkit
---------- /Library/Caches/com.apple.cloudkit/com.apple.cloudkit.launchservices.hostnames.plist
d--------- /Library/Caches/com.apple.iconservices.store

Expected Output: based on filewalker and os.FileInfo.Mode()

dtrwxrwxrwx /Library/Caches
-rw-r--r-- /Library/Caches/.DS_Store
drwxr-xr-x /Library/Caches/ColorSync
-rw-r--r-- /Library/Caches/ColorSync/com.apple.colorsync.devices
drwxr-xr-x /Library/Caches/com.apple.cloudkit
-rw-r--r-- /Library/Caches/com.apple.cloudkit/com.apple.cloudkit.launchservices.hostnames.plist
drwx--x--x /Library/Caches/com.apple.iconservices.store

Possible cause:
Walk.go line 244. ModeType is & with os.ModeType

Is this intentional?
