Knowing all the features of essential widgets is absolutely necessary to the completion of any Flutter project.
What does this mean?
Any StateLessWidget of Flutter comes with many features. Moreover, some of them depend on each other. For example, in Container widget, you can control the shape of the widget by providing some values. However, it will not work if you use borderRadius property at the same time.
Today we will direct our attention on Container widget. As the name suggests, it can contain many other widgets.
Let us jump from theory to practice – code. You will find everything explained in the following code snippet.
import 'package:flutter/material.dart';
class ContainerController extends StatelessWidget {
@override
Widget build(BuildContext context) {
return _containerController();
}
}
Widget _containerController() => Container(
//padding: EdgeInsets.all(8.00),
// it fills the whole container
//constraints: BoxConstraints.expand(),
alignment: Alignment.center,
//color: Colors.blue,
// we can adjust width and height
// to do that we need to commented out the constraints
width: 350.00,
height: 350.00,
// to skew the container
//transform: Matrix4.rotationZ(0.7),
decoration: BoxDecoration(
color: Colors.blue,
border: Border.all(
color: Colors.red,
width: 2.0,
style: BorderStyle.solid,
),
borderRadius: BorderRadius.all(Radius.circular(40.0)),
boxShadow: [
BoxShadow(
color: Colors.black54,
blurRadius: 20.0,
spreadRadius: 20.0,
),
],
gradient: LinearGradient(
begin: Alignment.centerLeft,
end: Alignment.centerRight,
colors: [
Colors.red,
Colors.white,
],
),
// to make shape active we need to comment out borderRadius property and vice versa
//shape: BoxShape.circle,
),
// padding will only work if the container padding is off
child: Padding(
padding: const EdgeInsets.all(10.0),
child: Text(
'Any App',
style: TextStyle(
fontSize: 45.00,
color: Colors.white,
),
),
),
);
