bottomNavigationBar using iPhone X - ios

Question

I have an issue with a bottomNavigationBar, the issue happens only on iPhone X, as there appears some padding below the BNB as if it were inside a SafeArea widget (and its not)
Well, how can I remove that padding? or maybe color it somehow?
This is my code for the build function
#override
Widget build(BuildContext context) {
return new Scaffold(
appBar: _buildAppBar(),
drawer: _buildDrawer(),
body: _isLoading
? Center(
child: CircularProgressIndicator(),
)
: new Container(
color: Colors.white,
child: _unauthorizedOrders()),
// floatingActionButton: FloatingActionButton(
// onPressed: () {},
// backgroundColor: primaryColor,
// child: Icon(Icons.flash_on, size: 30.0,),
// tooltip: 'Authorize Orders',
// ),
// floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
backgroundColor: Colors.red,
bottomNavigationBar: BottomAppBar(
child: Container(
height: 40.0,
color: primaryColor,
child: Row(
children: <Widget>[
// Padding(
// padding: const EdgeInsets.only(left: 10.0),
// child: Text(
// 'Orders: ${orders.length}',
// style: TextStyle(
// color: Colors.white,
// fontSize: 18.0,
// fontWeight: FontWeight.bold),
// ),
// ),
],
),
)),
);
}
EDIT: I have added the backgroundColor to the scaffold, removed the docked FAB and wrapped the body inside a container to paint it white, still doesn't work, I have updated the code above to show it

Answer 1

Use
SafeArea(
child: BottomAppBar(...)
);

Answer 2

A work-around will be to set the backgroundColor of your Scaffold to the same color as your BottomNavigationBar and have your content in a container with the color that you want.
Edit:
Here is a Sample code:
import 'package:flutter/material.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'BNB Demo on iPhone X',
theme: new ThemeData(
brightness: Brightness.dark,
primaryColor: Colors.black,
),
home: new MyHomePage(title: 'BNB Demo on iPhone X'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
int _counter = 0;
void _incrementCounter() {
setState(() {
_counter++;
});
}
#override
Widget build(BuildContext context) {
return new SafeArea(
child: new Scaffold(
appBar: new AppBar(
title: new Text(widget.title),
),
body: new Center(
child: new Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new Text(
'You have pushed the button this many times:',
),
new Text(
'$_counter',
style: Theme.of(context).textTheme.display1,
),
],
),
),
floatingActionButton: FloatingActionButton(
child: Icon(Icons.add, color: Colors.white,),
backgroundColor: Colors.black,
onPressed: _incrementCounter,
),
floatingActionButtonLocation: FloatingActionButtonLocation.centerDocked,
bottomNavigationBar: new BottomAppBar(
child: Container(
height: 40.0,
color: Colors.black,
),
),
),
);
}
}

I had the same problem with this bottomAppBar.
I only erased the color attibute.
Hope it helps to someone.
BottomAppBar(
elevation: 0.0,
shape: widget.notchedShape,
child: Container(
decoration: BoxDecoration(
borderRadius: BorderRadius.only(
topLeft: Radius.circular(20.0), topRight: Radius.circular(20.0)),
color: Colors.white),
child: Row(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceAround,
children: items)
),
color: Colors.teal[50]);
