The Flutter TextField has a really nice modeless dialog that appears above the field and stays visible even when the view is scrolled:
I need to create something very similar for when the user taps in a TextField (not when they select characters, which is when the copy-paste dialog appears). I created one using a Stack but quickly ran into trouble because the dialog was outside the pick box of the TextField so taps weren't detected by the GestureDetector (I posted here the issue here). A workaround posted in a couple spots was to code a custom OverlayContainer but I just notice it doesn't scroll with the TextField.
Is there a widget I'm overlooking that makes modeless dialogs easier?
