Loading custom fonts is often needed for websites, applications, and graphic design.
Today we'll investigate how to load Google fonts inside a flutter application.

The end result will look like this:

How to use Google Fonts in a Flutter application

If you want to work along with me, we start with the basic scaffolding app you can download from GitHub.

Installing the Google fonts package in Flutter

The first step is to load the package for google fonts.
To do so, add the Google fonts package in your pub spec.yml dependencies.

dependencies:
  flutter:
    sdk: flutter

  #Load the Google fonts package
  google_fonts: ^2.1.0
Enter fullscreen mode Exit fullscreen mode

Loading the font

The next step is to import the font package into our dart file. Let's open up the lib/main.dart file and place the following import there.

import 'package:google_fonts/google_fonts.dart';
Enter fullscreen mode Exit fullscreen mode

Now we can use any Google font we desire, but there are multiple options that we can use.

Loading a Google font for a specific Flutter widget

The most basic approach is to set the font on a specific Text widget. We already have one of those in our example, so let's pick a funky font and see it in action.

I'll be using the Pacifico font, because it will show you best how it works.

Now let's add this font as the style for our Text widget.

Text(
    'Hello World 👋',
    textDirection: TextDirection.ltr,
    style: GoogleFonts.pacifico(fontSize: 48),
)
Enter fullscreen mode Exit fullscreen mode

And that results in the following:

A pretty cool win already!

Loading a Google font for the app bar in Flutter

The same can be used to change the font of the app bar if you are using it.

appBar: AppBar(
  title: Text(
    'Testing Google Fonts',
    style: GoogleFonts.pacifico(),
  ),
),
Enter fullscreen mode Exit fullscreen mode

And it will look like this:

AppBar Google fonts

Loading Google fonts as a theme font

Another thing we could do is change the whole app theme font to be a Google font.

MaterialApp(
  theme: ThemeData(
    textTheme: GoogleFonts.pacificoTextTheme(),
  ),
)
Enter fullscreen mode Exit fullscreen mode

This will change all the text elements in our main app into this google font as well!

So if we have our main text like this:

Text(
    'Hello World 👋',
    textDirection: TextDirection.ltr,
),
Enter fullscreen mode Exit fullscreen mode

And that will result in:

Google font loaded as a theme

Note: the AppBar is not changed here as the theme font won't change that by default!
