bitsdojo_window

A Flutter package that makes it easy to customize and work with your Flutter desktop app window.

Features:

- Custom window frame - remove standard Windows titlebar and buttons
- Hide window on startup
- Show/hide window
- Move window using Flutter widget
- Minimize/Maximize/Restore/Close window
- Set window size, minimum size and maximum size
- Set window position
- Set window alignment on screen (center/topLeft/topRight/bottomLeft/bottomRight)
- Set window title

Currently working with Flutter desktop apps for Windows. macOS support is also planned in the future.

Getting Started

Install the package using pubspec.yaml

Inside your application folder, go to windows\runner\main.cpp and add these two lines at the beginning of the file:

#include <bitsdojo_window/bitsdojo_window_plugin.h>
auto bdw = bitsdojo_window_configure(BDW_CUSTOM_FRAME | BDW_HIDE_ON_STARTUP);

If you don't want to use a custom frame and prefer the standard Windows titlebar and buttons, you can remove the BDW_CUSTOM_FRAME flag from the code above.

If you don't want to hide the window on startup, you can remove the BDW_HIDE_ON_STARTUP flag from the code above.

Now go to lib\main.dart and add this code in the main function right after runApp(MyApp()); :

void main() {
  runApp(MyApp());

  // Add this code below

  doWhenWindowReady(() {
    var initialSize = Size(600, 450);
    appWindow.minSize = initialSize;
    appWindow.size = initialSize;
    appWindow.alignment = Alignment.center;
    appWindow.show();
  });
}

This will set an initial size and a minimum size for your application window, center it on the screen and show it on the screen.

You can find examples in the example folder.

Here is an example that displays this window:

import 'package:flutter/material.dart';
import 'package:bitsdojo_window/bitsdojo_window.dart';

void main() {
  runApp(MyApp());
  doWhenWindowReady(() {
    var win = appWindow;
    var initialSize = Size(600, 450);
    win.minSize = initialSize;
    win.size = initialSize;
    win.alignment = Alignment.center;
    win.title = "Custom window with Flutter";
    win.show();
  });
}

var borderColor = Color(0xFF805306);

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        debugShowCheckedModeBanner: false,
        home: Scaffold(
            body: WindowBorder(
                color: borderColor,
                width: 1,
                child: Row(children: [LeftSide(), RightSide()]))));
  }
}

var sidebarColor = Color(0xFFF6A00C);

class LeftSide extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return SizedBox(
        width: 200,
        child: Container(
            color: sidebarColor,
            child: Column(
              children: [
                WindowTitleBarBox(child: MoveWindow()),
                Expanded(child: Container())
              ],
            )));
  }
}

var backgroundStartColor = Color(0xFFFFD500);
var backgroundEndColor = Color(0xFFF6A00C);

class RightSide extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Expanded(
        child: Container(
            decoration: BoxDecoration(
              gradient: LinearGradient(
                  begin: Alignment.topCenter,
                  end: Alignment.bottomCenter,
                  colors: [backgroundStartColor, backgroundEndColor],
                  stops: [0.0, 1.0]),
            ),
            child: Column(children: [
              WindowTitleBarBox(
                  child: Row(children: [
                Expanded(child: MoveWindow()),
                WindowButtons()
              ])),
            ])));
  }
}

var buttonColors = WindowButtonColors(
    iconNormal: Color(0xFF805306),
    mouseOver: Color(0xFFF6A00C),
    mouseDown: Color(0xFF805306),
    iconMouseOver: Color(0xFF805306),
    iconMouseDown: Color(0xFFFFD500));

var closeButtonColors = WindowButtonColors(
    mouseOver: Colors.red[700],
    mouseDown: Colors.red[900],
    iconNormal: Color(0xFF805306),
    iconMouseOver: Colors.white);

class WindowButtons extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Row(
      children: [
        MinimizeWindowButton(colors: buttonColors),
        MaximizeWindowButton(colors: buttonColors),
        CloseWindowButton(colors: closeButtonColors),
      ],
    );
