Flutter - rounding border in opposite direction - flutter

I've found solution for this problem with help of encubos - thanks a lot! 😊. May code can be simplified - if you resolve this in better way, please share your code.
CODE:
appBar: PreferredSize(
preferredSize: Size.fromHeight(150.0),
child: Container(
decoration: BoxDecoration(
border: Border(
bottom: BorderSide(color: Colors.grey[200], width: 1.0),
top: BorderSide(color: Colors.lightBlue, width: 1.0)
)
),
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Container(
width: double.infinity,
decoration: BoxDecoration(
color: Colors.lightBlue,
border: Border.all(color: Colors.lightBlue, width: 0.0)
),
height: 100,
),
Container(
color: Colors.lightBlue,
child: Container(
width: double.infinity,
height: 72,
decoration: BoxDecoration(
border: Border.all(color: Colors.grey[200], width: 0.0),
color: Colors.grey[200],
borderRadius: new BorderRadius.vertical(
top: Radius.elliptical(150, 30),
),
)),
),
])
),
),
Result:
I've got problem with styling container bottom border. My goal is to rotate for 180 degrees bottom border of my top bar
Code:
appBar: PreferredSize(
preferredSize: Size.fromHeight(150.0),
child: Container(
decoration: BoxDecoration(
color: Colors.red,
borderRadius: new BorderRadius.vertical(
bottom: Radius.elliptical(150, 30)
)),
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
crossAxisAlignment: CrossAxisAlignment.center,
children: <Widget>[
new InkWell(
child: new Text(
'app',
style: TextStyle(
color: Colors.white,
fontWeight: FontWeight.bold,
fontSize: 24
)
),
onTap: () {
Navigator.of(context).pushNamed('/home');
},
),
],
),
),
),

One possible way to solve this is using the same idea in your code, but applying it to the top part of a Container below
See this code and image.
You need to ajust the color: white and the heights of the containers
Column(
crossAxisAlignment: CrossAxisAlignment.center,
children: [
Container(
color: Colors.red,
width: double.infinity,
height: 100,
),
Container(
color: Colors.red,
child: Container(
width: double.infinity,
height: 100,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: new BorderRadius.vertical(
top: Radius.elliptical(150, 30),
),
)),
),
])
Maybe you can improve this method and work from this.

How can I make the outer circles

I am trying to make the display feature for my app, but I am having a hard time making these outer circles, any input is appreciated
There is a way to draw using coordinates.
You can set the ratio using MediaQuery.of(context).size.
return Scaffold(
body: SafeArea(
child: Stack(
children: <Widget>[
Positioned(
top: 200,
left: 80,
child: Container(
width: 200,
height: 200,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(128.0),
border: Border.all(color: Colors.blue),
),
),
),
Positioned(
top: 225,
left: 105,
child: Container(
width: 150,
height: 150,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(128.0),
border: Border.all(color: Colors.blue),
),
),
),
],
),
),
);
Use this:
Container(
color: Colors.white,
child: Center(
child: Container(
width: 200,
height: 200,
decoration: BoxDecoration(
gradient: const LinearGradient(
colors: [Colors.white,Colors.white, Colors.red, Colors.red, Colors.white,Colors.white],
transform: GradientRotation(pi / 2),
),
borderRadius: BorderRadius.circular(128.0),
),
child: Center(
child: Container(
width: 198,
height: 198,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(120.0),
),
),
),
),
),
),
It leads to this output:
use stack widget and put 2 circle containers with different size as children in stack widget

I want to show it outside a light container like this
You need an external container to simulate the overlap effect.
Check the behavior of that component and try replicate your desired behavior.
Container(
height: 140.0,
width: 140.0,
color: Colors.amber, // set as transparent.
child: Stack(
children: [
Align(
alignment: Alignment.center,
child: Container(
height: 100.0,
width: 100.0,
decoration: const BoxDecoration(
color: Colors.red,
borderRadius: BorderRadius.all(Radius.circular(10))
),
),
),
Align(
alignment: Alignment.topRight,
child: Container(
width: 40.0, height: 40.0,
decoration: const BoxDecoration(
color: Colors.blue,
borderRadius: BorderRadius.all(Radius.circular(10))
)
),
),
],
),
),

you can use following code sample...change height according to your need...or use mediaquery for better result:
Container(
height: 275,
child: Stack(
children: [
Container(//container with background color
height: 250,
child: //other widgets
),
Positioned(
bottom: 0,
child: //button here
),
],

Outline border to widget in flutter

You can do this for simulate this design. It looks little bit of complicate but I can't find other way to do this. Hope that it will work for you.
Just make sure the bottom and the top container colors are same as the code.
Just call this MyMenuContent class to see this output.
class MyMenuContent extends StatelessWidget {
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Container(
height: MediaQuery.of(context).size.height / 2,
padding: EdgeInsets.all(10),
child: Stack(
children: [
Positioned(
top: 50,
child: Container(
height: MediaQuery.of(context).size.height / 12,
width: MediaQuery.of(context).size.width / 2,
decoration: BoxDecoration(
shape: BoxShape.rectangle,
borderRadius: BorderRadius.circular(12),
color: Colors.white,
border: Border.all(
color: Colors.black,
width: 1,
),
),
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: [
Icon(Icons.calendar_today),
SizedBox(width: 10),
