Introduction

Building polished Flutter UIs often involves stacking multiple widgets for padding, alignment, decoration, and text styling. The styled_widget package streamlines this process by providing extension methods and helper widgets that let you compose and customize your UI in a fluent, declarative style. In this tutorial, you’ll learn how styled_widget (and its close variant styled_widgets) simplifies styling, reduces boilerplate, and keeps your code readable.

Why styled_widget Is Useful

• Fluent API: styled_widget exposes extension methods on all widgets, so you can chain styling calls directly.

• Reduced Boilerplate: Instead of nesting Padding, Center, Container, and TextStyle widgets, you apply modifiers inline.

• Consistent Themes: You can define custom extensions to enforce consistent margins, font sizes, and colors across your app.

Getting Started

1. Add styled_widget to pubspec.yaml:
   

   dependencies:
     flutter:
       sdk: flutter
     styled_widget
   
   

2. Import in your Dart file:
   

   import 'package:flutter/material.dart';
   import 'package:styled_widget/styled_widget.dart';

Basic Usage

Here’s how to replace a nested widget tree with a single styled widget chain:

Without styled_widget:

Center(
  child: Padding(
    padding: EdgeInsets.all(16),
    child: Container(
      decoration: BoxDecoration(
        color: Colors.blue,
        borderRadius: BorderRadius.circular(8),
      ),
      child: Text(
        'Hello, Flutter!',
        style: TextStyle(color: Colors.white, fontSize: 18),
      ),
    ),
  ),
);

With styled_widget:

Text('Hello, Flutter!')
  .textColor(Colors.white)
  .fontSize(18)
  .padding(all: 16)
  .backgroundColor(Colors.blue)
  .borderRadius(all: 8)
  .alignment(Alignment.center);

This single chain replaces five nested widgets.

Practical Examples

Styling a Button

ElevatedButton(
  onPressed: () {},
  child: Text('Submit'),
)
  .padding(vertical: 12, horizontal: 24)
  .backgroundColor(Colors.green)
  .borderRadius(all: 6)
  .ripple()           // Adds ink splash
  .elevation(4);

Building a Card Row

Row(
  children: [
    Icon(Icons.star, color: Colors.orange),
    Text('Featured')
  ],
)
  .padding(all: 12)
  .borderRadius(all: 12)
  .backgroundColor(Colors.grey.shade200)
  .decorated(
    border: Border.all(color: Colors.orange, width: 2),
  );

Themed Extensions

You can define your own extension for a custom button style—ideal for a branded styled widget:

extension CustomButtonStyle on Widget {
  Widget primaryButton() => this
      .padding(vertical: 14, horizontal: 28)
      .backgroundColor(Colors.deepPurple)
      .borderRadius(all: 8)
      .ripple(bubbleColor: Colors.white24)
      .alignment(Alignment.center);
}

Use it in your UI:

Text('Save')
  .whiteText()
  .primaryButton();

Vibe Studio
