Appbar alignment - flutter

I am looking to align the name of the user next to the Welcome Back Text. Is there any way that this can be done in one line of code? Here is what I have right now.
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
brightness: Brightness.light,
backgroundColor: Colors.white,
elevation: 0,
title: Text("Welcome Back", style: TextStyle(color: Color.fromRGBO(49, 39, 79, 1), fontWeight: FontWeight.bold,fontSize: 20),),
actions: <Widget>[
new Container(
child: Text(
name, style: TextStyle(color: Color.fromRGBO(49, 39, 79, 1), fontWeight: FontWeight.bold,fontSize: 20)
),
),
Padding(
padding: const EdgeInsets.all(8.0),
child: CircleAvatar(
backgroundImage: NetworkImage(
imageUrl,
),
),
),
]),


Use for this case Row(...)
actions: <Widget>[
Row(
children: <Widget>[
Container(
child: Text(name, style: TextStyle(color: Color.fromRGBO(49, 39, 79, 1), fontWeight: FontWeight.bold,fontSize: 20))
),
Padding(padding: const EdgeInsets.all(8.0),
child: CircleAvatar(
backgroundImage: NetworkImage(imageUrl),
),
),
],
),
]
Btw: You don't need new. It is since Dart 2.0 optional.

I can't use the wrap widget side by side

*Create 20 container widgets side by side using the «wrap» widget
*Leave a 3-pixel space between them horizontally.
*Place the containers in the middle of the screen and type 1-2-3-4-5 in them.
I need to design a container widget in line with the above prompts, but when I ran the code I wrote, I saw that the containers are not side by side? What am I doing wrong?
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
void main()
{runApp(
MaterialApp(
debugShowCheckedModeBanner: false,
home:Scaffold(
appBar: AppBar(
title: Text(
"Containers in wraps",
style: TextStyle(color:Colors.greenAccent.shade400),
),
backgroundColor: Colors.black,
),
body: Padding(
padding: const EdgeInsets.all(15.0),
child: Wrap(
alignment: WrapAlignment.center,
spacing:3.0,
runAlignment: WrapAlignment.center,
runSpacing:3.0,
children: [
Expanded(
child: Container(
color: Colors.grey,
child: Center(
child: Text(
"1",
style: TextStyle(color: Colors.red,fontSize: 20),
),
),
),),
SizedBox(width:10,),
Expanded(
child: Container(
color: Colors.lightGreen,
child: Center(
child: Text(
"2",
style: TextStyle(color: Colors.red,fontSize: 20),
),
),
),),
SizedBox(width:10,),
Expanded(
child: Container(
color: Colors.lightGreen,
child: Center(
child: Text(
"3",
style: TextStyle(color: Colors.red,fontSize: 20),
),
),
),),
SizedBox(width:10,),
Expanded(
child: Container(
color: Colors.lightGreen,
child: Center(
child: Text(
"4",
style: TextStyle(color: Colors.red,fontSize: 20),
),
),
),),
SizedBox(width:10,),
Expanded(
child: Container(
color: Colors.blue,
child: Center(
child: Text(
"5",
style: TextStyle(color: Colors.red,fontSize: 20),
),
),
),),
],
),
),
),
),
);
}

Instead of Expanded use UnconstraindedBox. Following code should help:
void main() {
runApp(
MaterialApp(
debugShowCheckedModeBanner: false,
home: Scaffold(
appBar: AppBar(
title: Text(
"Containers in wraps",
style: TextStyle(color: Colors.greenAccent.shade400),

runAlignment: WrapAlignment.center,
runSpacing: 3.0,
children: [
UnconstrainedBox(

child: const Center(
child: Text(

style: TextStyle(color: Colors.red, fontSize: 20),

),
),
const SizedBox(

),
UnconstrainedBox(
child: Container(
color: Colors.lightGreen,

child: const Center(
child: Text(

const SizedBox(

child: const Center(
child: Text(

),
const SizedBox(

UnconstrainedBox(
child: Container(

I already have an appbar but another one?

I already have an appbar, but another one appears above it on some devices please help
Scaffold(
backgroundColor: kPrimaryColor,
body: SafeArea(
child: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Container(
height: 100,
width: 100,
child: Image(
image: AssetImage('images/eat.gif'),
),
),
Text(
'Anime Slash',
style: TextStyle(
fontSize: 24,
color: Colors.white,
fontFamily: 'SansitaSwashed'),
),
Text(
'انمي سلاش',
style: TextStyle(fontSize: 18, color: Colors.white),
),
SizedBox(
height: 40.0,
),
CircularProgressIndicator(
strokeWidth: 2.0,
backgroundColor: Colors.white,
),
],
),
),
),
);

If the parent widget have appbar it will show it. Just parent widget app bar or child app bar

Add buttons below the body

The code below (I shortened the code for simplicity) displays the characteristics of the device. I placed all the characteristics in the body and displayed them in a certain way. Tell me how I can make two buttons (marked in red in the photo) under the body. Or put them in the body? tell me the best way to do it.
return Scaffold(
appBar: AppBar(
automaticallyImplyLeading: false,
),
body: Align(
alignment: Alignment.topCenter,
child: Container(
constraints: const BoxConstraints(maxWidth: 800, maxHeight: 400),
decoration: BoxDecoration(
color: Colors.black,
borderRadius: BorderRadius.circular(5.0),),
child: SingleChildScrollView(
child: Card(
child: Column(
children: [
ListTile(
title: const Text('Brand:', style: TextStyle(fontWeight: FontWeight.w400, fontSize: 25)),
trailing: Text('${device.brand} ', style: const TextStyle(fontWeight: FontWeight.w400, fontSize: 20 ))),
const Divider(color: Colors.black, endIndent: 10, indent: 10),
ListTile(
title: const Text('Operation system:', style: TextStyle(fontWeight: FontWeight.w400, fontSize: 25)),
trailing: Text('${device.operation_system} ', style: const TextStyle(fontWeight: FontWeight.w400, fontSize: 20 ))),
],
),
),
)
),
));

You can use bottomNavigationBar on Scaffold
Scaffold(
bottomNavigationBar: Padding(
padding: const EdgeInsets.all(8.0), //the one you prefer
child: Row(
children: [
Expanded(
child: OutlinedButton(
onPressed: () {},
child: Text("NNNNNN"),
),
),
SizedBox(
//space between button
width: 16,
),
Expanded(
child: OutlinedButton(
onPressed: () {},
child: Text("NNNNNN"),
),
),
],
),
),
Also, you can wrap Container with Column widget
body: Column(
children: [
Container(...)//your widget
Padding(
padding: const EdgeInsets.all(8.0), //the one you prefer
child: Row(
children: [
Expanded(child: OutlinedButton(...)),
SizedBox(width:x),
Expanded(child: OutlinedButton(...)),
Full snippet on second approach
return Scaffold(
body: Column(
children: [
Container(
constraints: const BoxConstraints(maxWidth: 800, maxHeight: 400),
decoration: BoxDecoration(
color: Colors.black,
borderRadius: BorderRadius.circular(5.0),
),
child: SingleChildScrollView(
child: Card(
child: Column(
children: [
ListTile(
title: const Text('Brand:',
style: TextStyle(
fontWeight: FontWeight.w400, fontSize: 25)),
trailing: Text('${device.brand} ',
style: const TextStyle(
fontWeight: FontWeight.w400, fontSize: 20))),
const Divider(
color: Colors.black, endIndent: 10, indent: 10),
ListTile(
title: const Text('Operation system:',
style: TextStyle(
fontWeight: FontWeight.w400, fontSize: 25)),
trailing: Text('${device.operation_system} ',
style: const TextStyle(
fontWeight: FontWeight.w400, fontSize: 20))),
],
),
),
)),
// Spacer(), /// you you want at the bottom
Padding(
padding: const EdgeInsets.all(8.0), //the one you prefer
child: Row(
children: [
Expanded(
child: OutlinedButton(
onPressed: () {},
child: Text("NNNNNN"),
),
),
SizedBox(
//space between button
width: 16,
),
Expanded(
child: OutlinedButton(
onPressed: () {},
child: Text("NNNNNN"),
),
),

How to make icon button overlapping container widgets in Flutter?

I'm really new to Flutter. In the homepage, I intend to build the page something like this:
The other widgets are working pretty fine, but when I come to developing the double button like the design that overlapping the container widgets below, it's not working at all.
My first approach is using Stack which contain Positioned widgets (for the double button) and Container (for the other things). But, the Positioned widgets despite having a dummy child widget is not visible at all, whereas the Container is perfectly working. I don't know whether the Positioned is written in a wrong way, or else.
Here's the source code:
https://github.com/andre-nk23/packme/blob/master/lib/main.dart
Can anyone help me here? To make those two button overlapping the container? Thank you.
Note : I'm using several imported packages, please notify me if those packages affects the process of developing the overlap double button.

Hello Andrea, this is the necessary code which you can implement perfectly. Well, I have removed the redundant widgets which was been used to make the code cleaner.The stack was used by me to implement your question.

Have you tried Stack? You can approach this many ways, I just made this in a rush.have a look
Container(
height: 280,
width: 400,
child: Stack(
children: [
Positioned(
bottom: 0,
child: Container(
height: 250,
width: 400,
decoration: BoxDecoration(
color: Colors.pinkAccent,
borderRadius: BorderRadius.only(
topRight: Radius.circular(30),
topLeft: Radius.circular(30),
)
),
),
),
Positioned(
top: 0,
right: 100,
child: FloatingActionButton(
onPressed: (){},
child: Icon(
Icons.check_box
),
),
),
Positioned(
top: 0,
left: 100,
child: FloatingActionButton(
onPressed: (){},
child: Icon(
Icons.check_box
),
),
),
],
),
)

Use Row For Positioning both of the Buttons in container.
Container(
height: 280,
width: MediaQuery.of(context).size.width,
child: Stack(
children: [
Positioned(
bottom: 0,
child: Container(
height: 250,
width: 400,
decoration: BoxDecoration(
color: Colors.pinkAccent,
),
),
),
Positioned(
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly, children: [
FloatingActionButton(
onPressed: (){},
child: Icon(
Icons.person
),
),
FloatingActionButton(
onPressed: (){},
child: Icon(
Icons.face
),
),
],
),
),
],
),
)

Show me better way doing this in Flutter

I am just starting to code by my self in flutter. I
ve built this so far, here is the image. Can you show me what would be the better code? more cleaner. I used Row widget for it, but I guess I should maybe go with the Stack. Because now i want to add text field box in the middle of app bar that overflows in down direction.
child: Stack(
children: <Widget>[
Scaffold(
backgroundColor: Color.fromRGBO(255, 202, 6, 1),
appBar: PreferredSize(
preferredSize: Size.fromHeight(90.0),
child: Padding(
padding: const EdgeInsets.only(left: 20, top: 20, bottom: 10),
child: Row(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
CircleAvatar(backgroundImage: NetworkImage(
"https://res.cloudinary.com/demo/image/upload/w_200,h_200,c_thumb,g_face,r_max/face_left.png"),
radius: 32,
backgroundColor: Colors.white,
child: AppBar(
backgroundColor: Colors.transparent,
elevation: 0,
),
),
Padding(
padding: const EdgeInsets.only(left: 13, top: 8),
child: Text(
'Someones Name',
textAlign: TextAlign.center,
overflow: TextOverflow.ellipsis,
style: TextStyle(
fontWeight: FontWeight.bold, fontSize: 20),
),
),
Padding(
padding: const EdgeInsets.only(left: 100, bottom: 30),
child: Switch(
inactiveThumbColor: Colors.white,
activeColor: Colors.grey[700],
value: false,
onChanged: (bool state) {
print(state);
},
),
),
],
),
),
),
body: Container(
height: 800,
width: 500,
decoration: BoxDecoration(
color: Color.fromRGBO(251, 251, 251, 1),
borderRadius: BorderRadius.vertical(
top: Radius.circular(15),
),
),
),
),
],
overflow: Overflow.visible,
),
);

You can use the power of Axis Alignment and the Flex items. This example below get the result that you want.
Scaffold(
backgroundColor: Color.fromRGBO(255, 202, 6, 1),
appBar: PreferredSize(
preferredSize: Size.fromHeight(90.0),
child: Container(
margin: EdgeInsets.only(top: 20),
padding: EdgeInsets.all(30),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Row(
children: <Widget>[
CircleAvatar(
backgroundImage: NetworkImage(
"https://res.cloudinary.com/demo/image/upload/w_200,h_200,c_thumb,g_face,r_max/face_left.png"),
radius: 32,
backgroundColor: Colors.white,
),
Container(
margin: EdgeInsets.only(left: 10),
child: Text(
'Name',
textAlign: TextAlign.center,
overflow: TextOverflow.ellipsis,
style:
TextStyle(fontWeight: FontWeight.bold, fontSize: 20),
),
),
],
),
Flexible(
child: Switch(
inactiveThumbColor: Colors.white,
activeColor: Colors.grey[700],
value: false,
onChanged: (bool state) {
print(state);
},
),
),
],
),
),
),
body: Container(
decoration: BoxDecoration(
color: Color.fromRGBO(251, 251, 251, 1),
borderRadius: BorderRadius.vertical(
top: Radius.circular(15),
),
),
),
);
