I'm making a dynamic form builder and to test it I have been adding various forms of form fields to it. While adding the chips input field, I have noticed something.
If the choice chip is at the bottom of the form it will throw the following error message:
[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: This widget has been unmounted, so the State no longer has a context (and should be considered defunct).

If I add some padding and move the page up, it will work fine. But eventually, the closer it gets to the bottom (bellow a padding of 34 in a list view builder and fully scrolled down) the above error message throws and hides the keyboard, resetting any chips that may have been already added. So if you tap the field when it's visible, but not 34 pixels away from the bottom edge it throw the unmounted error, otherwise works as expected.
