Plumix

Flutter-inspired UI framework for .NET — build declarative, widget-based UIs in C# with Flutter's Widget/Element/RenderObject architecture.

plumix.net · NuGet packages

Vision

• Keep Widget/Element/RenderObject architecture as close as practical to Flutter.
• Make rewriting controls from Flutter (Dart) to C# straightforward, with minimal conceptual translation.
• Reuse Avalonia mostly as platform infrastructure: app/window host, lifecycle, input plumbing, and drawing backend abstractions.
• Keep layout and paint behavior inside this framework's render layer.

Definition of Done

1. App UI is built with Flutter-like widgets and lifecycle primitives (StatefulWidget, State, SetState, reconciliation).
2. Render/layout/paint behavior is framework-owned (RenderObject/RenderBox/render pipeline), not Avalonia-control-driven UI logic.
3. Samples demonstrate real framework usage via widget host flow, not only low-level render demos.
4. Core primitives are stable and close enough to Flutter semantics for practical Dart-to-C# control porting.

Example

using Avalonia.Media;
using Plumix.Widgets;

namespace MyApp;

public sealed class MyApp : StatelessWidget
{
    public override Widget Build(BuildContext context)
    {
        return new Scaffold(
            body: new Center(
                child: new Column(
                    mainAxisAlignment: MainAxisAlignment.Center,
                    children:
                    [
                        new Text(
                            "Hello, Plumix!",
                            style: new TextStyle(fontSize: 32, fontWeight: FontWeight.Bold)
                        ),
                        new SizedBox(height: 16),
                        new Text("Flutter-like widgets, powered by .NET and Avalonia."),
                        new SizedBox(height: 24),
                        new ElevatedButton(
                            onPressed: () => { /* handle tap */ },
                            child: new Text("Get Started")
                        )
                    ]
                )
            )
