Some Notices
- If you want to use default navigation bar, you can use simply this way;
CupertinoPageScaffold(
navigationBar: DefaultCupertinoNavigationBar( // same as CupertinoNavigationBar but little differencies
backgroundColor: CupertinoColors.systemGrey.withOpacity(0.5),
middle: const Text('CupertinoNavigationBar Sample'),
)
);
- Without using default navigation bar, You can use SuperCupertinoNavigationBar without largeTitle. Simply use this value;
CupertinoPageScaffold( //inside CupertinoPageScaffold
child: SuperCupertinoNavigationBar(
largeTitleType: AppBarType.NormalNavbarWithoutSearch, // This will make appbar like CupertinoNavigationBar
middle: Text("Home")
slivers: [
// Any Sliver here
],
),
);
in these case, you should be aware of you will use custom scroll view and sliver widgets.
