FeatureFlags for Avalonia

FeatureFlags for Avalonia is a lightweight library that allows you to enable or disable UI components dynamically based on feature flags. It provides a simple and intuitive way to control the visibility and activity of controls directly from your AXAML files using attached properties.

Getting Started

Installation

Add the library to your Avalonia project via NuGet:

Install-Package FeatureFlags.Avalonia

Usage

1. Define Feature Flags

Define your feature flags in your Program.cs:

public static AppBuilder BuildAvaloniaApp()
=> AppBuilder.Configure<App>()
    .UsePlatformDetect()
    .WithInterFont()
    .LogToTrace()
    
    .UseIniForFeatureFlags("FeatureFlags.ini")
    .UseJsonForFeatureFlags("FeatureFlags.json")
    .UseDicionaryForFeatureFlags(new Dictionary<string, bool>
    {
        { "Feature1", true },
        { "Feature2", false }
    })
;

2. Use in AXAML

Add the FeatureFlags namespace to your AXAML file and use the attached properties:

<Window xmlns="https://github.com/avaloniaui"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="using:YourNamespace">
    <StackPanel>
        <Button Content="Visible if FeatureA is Enabled"
                local:FeatureFlags.IsVisible="FeatureA" />
        <Button Content="Active if FeatureB is Enabled"
                local:FeatureFlags.IsActive="FeatureB" />
    </StackPanel>
</Window>

IsVisible: Controls the visibility of a control based on a feature flag.

IsActive: Enables or disables a control based on a feature flag.

FeatureManager Methods:

IsFeatureEnabled(string featureName): Checks if a feature flag is enabled.
