fluent_ui

Design beautiful native windows apps using Flutter

Unofficial implementation of Fluent UI for Flutter. It's written based on the official documentation

Motivation #

Since flutter has Windows support (currently in stable under an early release flag as of 11/03/2021), it's necessary to have support to its UI guidelines to build apps with fidelity, since it has support for Material and Cupertino. See this for more info on the offical fluent ui support

Roadmap #

Currently, we've only done the desktop part of the library, so you can import the library as one itself:

import 'package:fluent_ui/fluent_ui';

Note: this does not mean you can't use this library anywhere else. You can use it wherever you want

Futurely, once the desktop part of this library gets mature, web and mobile will also be supported. See also:

Also, futurely there will be a way to get the current device accent color. For more info, see accent color

You can use the Theme widget to, well... theme your widgets. You can style your widgets in two ways:

Using the FluentApp widget

FluentApp(
  title: 'MyApp',
  style: Style(
    ...
  ),
)

Using the Theme widget

Theme(
  style: Style(
    ...
  ),
  child: ...,
),

Icons #

Inside your app, you use icons to represent an action, such as copying text or navigating to the settings page. This library includes an icon library with it, so you can just call Icons.[icon_name] in any Icon widget:

Icon(Icons.add_regular)

To style icons, you can use IconStyle in the app Style or use the property style in the Icon widget. You can see the list of icons here

Colors #

This library also includes the Fluent UI colors with it, so you can just call Colors.[color_name]:

TextStyle(color: Colors.black)

Avaiable colors:

Colors.transparent
Colors.white
Colors.black
Colors.grey
Colors.yellow
Colors.orange
Colors.red
Colors.magenta
Colors.purple
Colors.blue
Colors.teal
Colors.green

Accent color

Common controls use an accent color to convey state information. By default, the accent color is Colors.blue. However, you can also customize your app's accent color to reflect your brand:

Style(
  accentColor: Colors.blue,
)

Brightness #

You can change the style brightness to change the color of your app.

Brightness.light
Brightness.dark

It defaults to the brightness of the device. (MediaQuery.of(context).brightness)

Typography #

To set a typography, you can use the Style class combined with the Typography class:

Style(
  typography: Typography(
    caption: TextStyle(
      fontSize: 12,
      color: Colors.black,
      fontWeight: FontWeight.normal,
    ),
  ),
)

Font

You should use one font throughout your app's UI, and we recommend sticking with the default font for Windows apps, Segoe UI. It's designed to maintain optimal legibility across sizes and pixel densities and offers a clean, light, and open aesthetic that complements the content of the system.
