Motivation and maintenance #

Since Flutter has stable Windows support, it's necessary to have support to its UI guidelines to build apps with fidelity, the same way it has support for Material and Cupertino. See this for more info on the offical fluent ui support

This is an open-source package, which means that anyone can contribute to it. However, I, bdlukaa, am the only one actively maintaining it, so it may take some time to review and merge pull requests. If you want to support the project, you can become a patron:

Installation #

Add the package to your dependencies:

  fluent_ui: ^4.4.0


    git: https://github.com/bdlukaa/fluent_ui.git

Finally, run dart pub get to download the package.

Projects using this library should use the stable channel of Flutter

Badge #

Are you using this library on your app? You can use a badge to tell others:

Add the following code to your README.md or to your website:

<a title="Made with Fluent Design" href="https://github.com/bdlukaa/fluent_ui">

Accent color #

Common controls use an accent color to convey state information. Learn more.

By default, the accent color is Colors.blue. However, you can also customize your app's accent color to reflect your brand:

  accentColor: Colors.blue,

To use the system's accent color, you can use the plugin system_theme made by me :). It has support for (as of 21/01/2023) Android, Web, MacOS, Windows, Xbox and Linux (GTK 3+).

import 'package:system_theme/system_theme.dart';

  accentColor: SystemTheme.accentColor.accent.toAccentColor(),

In PR#216 we added support for new localizations in FluentUI Widgets.

If you want to contribute adding new localizations please follow this steps:
