How do I use a list in dynamic block to create multiple resources for each elements

Terraform

I am trying to use a list in dynamic block to create multiple resources for each elements:

variables file like:

variable "example" {
   description = "(optional) describe your variable"
   type    = map(any)
   default = {
       "key" = {
           "value" = [1, 2]
       }
}

Now in dynamic block trying to use the value to create multiple resources with each elements from list:

dynamic "block" {
  for_each = [for v in var.example : {
    value = v.value
  }]
  content {
    value = block.value
  }
}

But its not taking each values. Instead taking the list seems.
How to achieve this?

TIA
