PrismEmptyState class
A friendly empty state with an icon, a title, a subtitle and an action.
Every list screen needs one. Takes the ambiguity out of whether the list is empty because there is nothing to show, or because it failed to load.
PrismEmptyState(
icon: Icons.note_add_outlined,
title: 'No notes yet',
subtitle: 'Tap the + button to add your first note.',
actionLabel: 'Add a note',
onAction: createNote,
)
