Introduction
In the ever-evolving world of Flutter, developers are constantly seeking new ways to add visual appeal to their applications. One powerful tool that Flutter offers is the ColorFiltered widget. With ColorFiltered, you can effortlessly apply captivating visual effects to your UI elements, enhancing the overall user experience. In this blog post, we will dive into the capabilities of the ColorFiltered widget, explore its usage, and provide a practical example to help you get started.
Understanding ColorFiltered:
The ColorFiltered widget in Flutter allows you to apply a colour filter to its child widget. This filter modifies the visual appearance of the child, enabling you to achieve various effects like grayscale, sepia, or tinting. This widget comes in handy when you want to create engaging UI elements or convey specific moods or themes through colour manipulation.
Usage
Let's assume that you have an image that you want to display by blending it with saturation, with the help of ColorFiltered widget you can easily do it.
Paste the below code inside your main.dart file 👇
import 'package:flutter/material.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
debugShowCheckedModeBanner: false,
title: 'ColorFiltered Widget Demo',
theme: ThemeData(
colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
useMaterial3: true,
),
home: const ColorFilteredWidgetDemo(),
);
}
}
class ColorFilteredWidgetDemo extends StatefulWidget {
const ColorFilteredWidgetDemo({super.key});
@override
State<ColorFilteredWidgetDemo> createState() =>
_ColorFilteredWidgetDemoState();
}
class _ColorFilteredWidgetDemoState extends State<ColorFilteredWidgetDemo> {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('ColorFilter Widget Demo'),
centerTitle: true,
),
body: Center(
child: ColorFiltered(
colorFilter:
const ColorFilter.mode(Colors.greenAccent, BlendMode.saturation),
child: Image.asset('assets/ironman.jpg'),
),
),
);
}
}The above 👆 code snippet displays an image of Iron Man on the screen with a green accent color filter applied to it. The color filter specifically affects the saturation of the image, making it appear more vibrant or desaturated based on the blending mode and color chosen.
