How to set Linear Gradient Background on Container in Flutter App
Introduction
Linear Gradient is a great way to add visual appeal to your Flutter app. It can be used to create a beautiful and unique background for your containers. In this article, we will explore how to set a linear gradient background on a container in a Flutter app.
Understanding Linear Gradient
A linear gradient is a type of gradient that progresses in a linear direction, from one color to another. It can be used to create a variety of effects, from subtle background textures to dramatic color shifts.
Setting Linear Gradient Background on Container
To set a linear gradient background on a container in Flutter, you can use the `Container` widget and its `decoration` property. The `decoration` property takes a `BoxDecoration` object, which has a `gradient` property that can be used to set the linear gradient.
“`dart
import ‘package:flutter/material.dart’;
class LinearGradientContainer extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Container(
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Colors.blue, Colors.red],
begin: Alignment.topLeft,
end: Alignment.bottomRight,
),
),
child: Center(
child: Text(‘Linear Gradient Container’),
),
);
}
}
“`
Customizing Linear Gradient
You can customize the linear gradient by changing the `colors`, `begin`, and `end` properties of the `LinearGradient` object. The `colors` property takes a list of colors that will be used to create the gradient. The `begin` and `end` properties take an `Alignment` object that specifies the direction of the gradient.
“`dart
import ‘package:flutter/material.dart’;
class CustomLinearGradientContainer extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Container(
decoration: BoxDecoration(
gradient: LinearGradient(
colors: [Colors.yellow, Colors.green, Colors.blue],
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
stops: [0.2, 0.5, 0.8],
),
),
child: Center(
child: Text(‘Custom Linear Gradient Container’),
),
);
}
}
