GoogleFonts library something we can’t avoid when it comes to finding freely available fonts for our UIs. In this article, I’m going to show you how to use the official GoogleFonts Plugin for Flutter.
What’re the benefits of using the official plugin?
- You don’t need to store
.otffonts files in your assets directory and mapped in the pubspec. Instead, the package will fetch fonts via HTTP at runtime, and cache in the app’s file system. So you can reduce your app bundle size and saves your development time.
- The plugin will automatically update your font’s to the there latest version.
- You can test your app UI with different fonts with less effort.
- You can still pre-bundle your fonts with this package if you wish to do so.
How to import Google fonts plugin to your app?
First we need to import GoogleFonts plugin into our app. We need to follow 3 simple steps to get this done.

Text( 'Hello World!', textDirection: TextDirection.ltr, style: GoogleFonts.roboto( textStyle: TextStyle(color: Colors.blue, fontSize: 32) )
