This is a simle custom window for the FluentUI design using Bitsdojo Window and Flutter Acrylic. It works on Windows, Linux and MacOS, but it's naturally the best on Windows.

Features

• No OS-TitleBar
• Background blur and other transparency effects
• Custom window controls

Getting started

First, setup Bitsdojo Window, then just wrap your content in FluentWindow.

Usage

import 'dart:io';

import 'package:bitsdojo_window/bitsdojo_window.dart';
import 'package:fluent_ui/fluent_ui.dart';
import 'package:flutter_acrylic/flutter_acrylic.dart';

Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  // This comes from Flutter Acrylic
  await Window.initialize();

  if (Platform.isWindows) {
    await Window.hideWindowControls();
  }

  runApp(const MyApp());

  if (!Platform.isMacOS) {
    // This comes from Bitsdojo Window
    doWhenWindowReady(() {
      appWindow
        ..minSize = Size(640, 360)
        ..size = Size(1300, 800)
        ..alignment = Alignment.center
        ..show();
    });
  }
}

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

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  @override
  Widget build(BuildContext context) {
    return FluentApp(
      title: 'Example App',
      theme: FluentThemeData(
        brightness: Brightness.dark,
        // Important if you want to use a Scaffold and have Flutter Acrylic's effects
        scaffoldBackgroundColor: Colors.transparent, 
      ),
      home: FluentWindow(
        title: // Optional, the title of you App if you want to show one.
               // It will appear on the far left next to the MenuBar
        menuBar: // Optional, this will appear next to the title. Intended for the fluent_ui MenuBar,
                 // but you can add your own custom one if you want ,
        child: // Your Flutter App,
      ),
    );
  }
}
