Getting a stable Id of item

[pixtur]

Version/Branch of Dear ImGui:

Version: 1.70
Branch: master

Back-end/Renderer/Compiler/OS

Back-ends: imgui.net
Operating System: win10

My Issue/Question:
I want to implement a custom DragFloat compoment. I believe for this I need an item-identifier for that is stable between frames. Is there an API to access the id the of last item? I searched in imgui.h but couldn't find anything.

in issue #1537 i found the following code:

    if (g.LastActiveId == g.CurrentWindow->GetID(str_id))// && g.LastActiveIdTimer < ANIM_SPEED)
    {
        float t_anim = ImSaturate(g.LastActiveIdTimer / ANIM_SPEED);
        t = *v ? (t_anim) : (1.0f - t_anim);
    }

But I believe that this is not exposed on the default API. Since I using imgui.net I only have access to the main API.

After re-reading the imgui.h, I realized, that GetID(string) is just the method, I was looking for. I guess I got confused by the string parameter.
