Introduction
Flutter is a powerful and flexible mobile app development framework that allows developers to create beautiful, responsive, and performant apps for Android and iOS. One of the key features of Flutter is its ability to easily style and customize widgets to fit your app's design.
In this tutorial, we will cover some of the basics of styling widgets in Flutter. We will look at how to style text and fonts, work with colors, customize buttons, design containers, and create layouts.
Styling Text and Fonts
Flutter makes it easy to style text and fonts in your app. You can use the Text
widget to display text and apply various styles to it. Here's an example of how to change the font size of a Text
widget:
Text( 'Hello, World!', style: TextStyle(fontSize: 20), )
In the code above, we set the fontSize
property of the TextStyle
to 20
to change the font size of the text.
Output:

You can also change other properties of the TextStyle
to apply different styles to the text, such as color
, fontWeight
, fontStyle
, and fontFamily
.
Here's an example of how to apply different styles to a Text
widget:
Text( 'Hello, World!', style: TextStyle( fontSize: 20, color: Colors.red, fontWeight: FontWeight.bold, fontStyle: FontStyle.italic, fontFamily: 'Roboto', ), )
In the code above, we set the color
property of the TextStyle
to Colors.red
to change the color of the text. We also set the fontWeight
property to FontWeight.bold
to make the text bold, and the fontStyle
property to FontStyle.italic
to make the text italic. Finally, we set the fontFamily
property to 'Roboto'
to use the Roboto font.
Output:

Working with Colors
Colors play a crucial role in designing beautiful apps. Flutter provides a wide range of colors that you can use in your app.
Here's an example of how to use the Colors
class to set the background color of a Container
widget:
Container( color: Colors.blue, )
In the code above, we set the color
property of the Container
to Colors.blue
to set the background color to blue.
Output:

You can also use other properties of the Colors
class to set the color of text, buttons, and other widgets.
Designing Containers
Containers are used to group and layout other widgets. Flutter provides several properties that you can use to customize the appearance of a Container
widget, such as padding
, margin
, and decoration
.
Here's an example of how to use the decoration
property to add a border to a Container
:
Container( decoration: BoxDecoration( border: Border.all( color: Colors.black, width: 2, ), ), child: Text('Hello, World!'), )
In the code above, we set the decoration
property of the Container
to a BoxDecoration
with a Border
property to add a black border around the container. We also set the width
property of the Border
to 2
to make the border thicker.
You can also use the padding
and margin
properties to add spacing around the container and its child widgets.
Here's an example of how to use the padding
property to add padding around a Container
:
Container( padding: EdgeInsets.all(10), child: Text('Hello, World!'), )
In the code above, we set the padding
property of the Container
to EdgeInsets.all(10)
to add 10
pixels of padding around the container.
Output:

Layouts
Layouts are used to position widgets on the screen. Flutter provides several built-in layouts that you can use in your app, such as Column
, Row
, and Stack
.
Here's an example of how to use a Column
layout to stack multiple widgets vertically:
Column( children: [ Text('Widget 1'), Text('Widget 2'), Text('Widget 3'), ], )
In the code above, we create a Column
widget with three Text
widgets as its children. The Column
layout stacks the Text
widgets vertically.
Output:

You can also use the Row
layout to position widgets horizontally.
Here's an example of how to use a Row
layout to position two widgets side-by-side:
Row( children: [ Text('Widget 1'), Text('Widget 2'), ], )
In the code above, we create a Row
widget with two Text
widgets as its children. The Row
layout positions the Text
widgets side-by-side.
Output:
