How to dynamically update children while preserving the Speed Dial open?

[ozkayas]

What I need is a similar flow like this: I already searched and read these issues: #220, #259 and #181, tried to implement what is already told. However can not figure it out. Tried to set closeManually and visible attributes using setState or ValueNotifiers, can not do it yet. Am I missing something? Or is this still impossible.
