copied to clipboard
Then, run flutter packages get in your terminal.
Usage 💻 #
To use this package you must first wrap your top most widget with Portal as this package uses flutter_portal to show the suggestions list.

[Portal], is the equivalent of [Overlay].
This widget will need to be inserted above the widget that needs to render
under your overlays.
If you want to display your overlays on the top of everything, a good place
to insert that [Portal] is above MaterialApp:
Portal(
child: MaterialApp(
...
)
);
copied to clipboard
(works for CupertinoApp too)
This way [Portal] will render above everything. But you could place it
somewhere else to change the clip behavior.
