Is there FormBuilderDropdown lazy loading items?

[fehernyul]

Hi,

I need that function which allow me to get the FormBuilderDropdown items when I tap/push on down-arrow in the side.
When it's dropping-down/opening, this should be call an HTTP request for the real/big FormBuilderDropdown-items.
BUT before it this need to show the initialValue!

Because of this error message I got all the time:
"There should be exactly one item with [DropdownButton]'s value: OPERATINGCURRENTACCOUNT. \nEither zero or 2 or more [DropdownMenuItem]s were detected with the same value"

Maybe you are receiving two instances of something that has the same value. i.e: ['Some Value', 'Some Value']
