How to remove automatic SafeArea from ListView?

From the ListView documentation:

By default, ListView will automatically pad the list's scrollable extremities to avoid partial obstructions indicated by MediaQuery's padding. To avoid this behavior, override with a zero padding property.

So the fix is:

ListView(
  padding: EdgeInsets.zero,
  ...
);

Found this solution as well

MediaQuery.removePadding(
  context: context,
  removeTop: true,
  child: ListView(...),
)
