Index based values pass in the terraform resource block

Question

I would like to get a index based values in the resource block values Current setup:

    locals{
       Vvn = { 
     "0" = "sam1"
      "1" = " sam2"
      "3" = "sam3"
}

I need to get this vvn values sam1, sam2, sam3 based on index keys in the below resource block.

       resource "null_resource" 
     "sample" {
           for_each = var.sampleconfig
           name = each.value.flag==true? { for n in range(length(local.vvn)): local.vvn[n]] : "string.each.value.name"
}
}

But it throws error and cannot able to get index based value .I don't want to pass local variables vvn to for_each since already iam using another map. I just tried out index, lookup functions but no luck. Expected output :

In resource block I want touse name value index based values of locals.vvn each by each. Any help appreciated.

Thanks.

To get value of a map based on index, you can use values. For example,

name = values(local.Vvn)[0]

But this returns values based on exicographical order order, not based on keys.

To use your keys, you can:

name = local.Vvn[0]
