system_fonts

A Flutter package that allows users to easily load system fonts on Windows, MacOS, and Linux platforms.

Features

• Load system fonts dynamically in Flutter applications.
• Support for Windows, MacOS, and Linux platforms.
• Supports ttf and otf font formats.
• Simple API for loading and using system fonts in your Flutter project.

Installation

1. Add the following line to your pubspec.yaml file in the dependencies section:

dependencies:
    system_fonts: ^VERSION

Usage

Font family names are the font file name in the system without extensions. For example to change font family of Text widget to arial(arial.ttf), use loadFont(String fontName) method with parameter arial, this function will load arial.ttf file in the system and return font family name.

class Example extends StatefulWidget {
  const Example({super.key});

  @override
  State<Example> createState() => _ExampleState();
}

class _ExampleState extends State<Example> {
  String fontFamily = '';

  @override
  void initState() {
    super.initState();
    SystemFonts().loadFont('arial').then((value) {
      setState(() {
        fontFamily = value.toString();
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Text('this text will use arial font', style: TextStyle(fontFamily: fontFamily));
  }
}

You can load all the fonts on the system with loadAllFonts() method which returns all the available font family names and then you can use any font in any widget.

You can specify a font folder to load every font inside it and then use them in flutter with addAdditionalFontDirectory(String path) method.

You can add any font from full path with loadFontFromPath(String path) method.

You can list all available font family names to use with getFontList() method.

There is also a widget called SystemFontSelector() for list and select fonts and example app shows how to use it.
