[ERROR:flutter/lib/ui/ui_dart_state.cc(186)] Unhandled Exception: MissingPluginException(No implementation found for method setMinWindowSize on channel desktop_window)

How to solve this problem?

Seems for me I'm missing some functions like setBorders() ?

In Linux on-screen keyboard enabled, and desktop-window set to fullscreen, the onscreen keyboard open and close automatically when I click a text filed, it's stay in normal screen.

normal mode (without fullscreen) is working without any issue.

the current setFullscreen works more like a .maximize() so I think we should call it that too.
Behavour should be .maximize() = .toggleFullScreen() and .maximise(true) = .setFullScreen(true) and .maximize(false) = .setFullscreen(false).
.isMaximized should be a getter for .getFullScreen();

the current fullcreen on Linux should be replaced with a maximize implementation and on macos .kioskMode(bool kioskMode) should do the same as maximize, but on Linux and Windows it should make the window fullscreen without any menu bars or the taskbar.

How to set it to full screen?

setMinWindowSize not working after toggleFullScreen

Useful for for example overlays

Adding linux support would be really helpful.

At the moment, there is no way to bring the application window to the front of the screen or activate the window using this plugin. To my knowledge (at least on macOS), calling setWindowSize asynchronously may cause the app to crash due to NSApplication.shared.mainWindow being nil when the window is out of focus.

I've already implemented this for macOS in a separate plugin, but it would be very fitting to add support for all the platforms here in one unified plugin.

setting maximum and minimum window size is not working in the same time on linux
I am using KDE Plasma 5 as my desktop environment

only the first used method works
e.g.
if I used DesktopWindow.setMaxWindowSize(size); then DesktopWindow.setMinWindowSize(size);
only maximum size works

Upon trying to retrieve the window size, the error "(MAINWINDOW_NOT_FOUND, GtkWindow not found, null, null)" is thrown.

No matter where I attempt to retrieve the window size, be it on the loading of the app or by the press of a button after the window is already loaded and fully initialised, this error still occurs.

Presently the plugin only supports Desktop platforms (macos, linux and windows). When compiling a project that depends on desktop_window for mobile platform (android and ios), compilation will always fail as there are no modules set up for this plugin.
I'm not sure if this plugin could have an overloaded usage for the mobile platform but a simple no-op implementation would be useful to allow consumption in projects that have a single codebase for mobile and desktop platforms.

What do you think? I am willing to raise a PR if that helps.

Hello,
In macOS, there is a problem where the generated file from flutter is throwing an error. Although the program runs fine when using 'flutter run' when trying a native build from XCode an error is immediately thrown and is picked up as a compiler error.

If anyone knows the solution to this problem please let me know.

Thanks,
Rhino Inani

A screenshot of the problem is shown below.

I tried to add some code like the following in my main.dart.

  if (!kIsWeb && (Platform.isWindows || Platform.isLinux || Platform.isMacOS)) {
    var size = Size(config.windowWidth, config.windowHeight);
    // disable window resizing
    await DesktopWindow.setWindowSize(size);
    await DesktopWindow.setMinWindowSize(size);
    await DesktopWindow.setMaxWindowSize(size);
  }

However, I got no response on windows 11, I have tested it ok on windows 10. If I comment these pieces of code or change it to use window_size of github.com/google/flutter-desktop-embedding, it works too.

I tried both this package and window_size of flutter-desktop-embedding. They are all first show the initial default sized window, then resize or move it. So a window blink will still exist.

Is there any way to set the initial size of the startup window without show-resize-move steps?

  desktop_window: ^0.3.0
  window_size:
    git:
      url: git://github.com/google/flutter-desktop-embedding.git
      path: plugins/window_size

import 'package:desktop_window/desktop_window.dart';
import 'package:flutter/material.dart';
import 'package:system_network_proxy/app.dart';
import 'package:system_network_proxy/flutter_configuration.dart';
import 'package:system_network_proxy/service.dart';
import 'dart:io' show Platform;
import 'dart:math' as math;
import 'package:window_size/window_size.dart' as window_size;

/// global configuration from yaml
FlutterConfiguration config;
void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  // await DesktopWindow.setWindowSize(Size(500, 300));
  var window = await window_size.getWindowInfo();
  if (window.screen != null) {
    final screenFrame = window.screen.visibleFrame;
    final width = 500.0;
    final height = 300.0;
    final left = ((screenFrame.width - width) / 2).roundToDouble();
    final top = ((screenFrame.height - height) / 3).roundToDouble();
    final frame = Rect.fromLTWH(left, top, width, height);
    window_size.setWindowFrame(frame);
    window_size.setWindowMinSize(Size(1.0 * width, 1.0 * height));
    window_size.setWindowMaxSize(Size(1.0 * width, 1.0 * height));
    window_size.setWindowTitle('System Network Proxy (${Platform.operatingSystem})');
  }
  config = await FlutterConfiguration.fromAsset('assets/config.yaml');
  await Service().init();
  runApp(App());
}

Add full screen without system default top bar on Windows.

Partly the same as #20

After setting this, I am still able to make the desktop macOs app smaller than 400x400 in width and height.

Is there something additional that I need to perform apart from DesktopWindow.setMinWindowSize() to not let it be smaller than what I am setting in the width and height here?

After Updating Flutter to 2.2.2 on MacOS I receive a "MainWindow not found" message from the Future of the function "setMinWindowSize".

I'm running the application on MacOS 10.15.6

I keep getting this error, but I have 3.16.2 but it keeps throwing me this build error.

stayOnTop is inconsistent across operating systems. On macOS it lets a window stay onTop of the parent window, but on linux and windows it pins a window at the top position of the z-stack, at least as far as I know

Focus is an undefined method

await DesktopWindow.setFullScreen(true);

What could I have done wrong?

It would be nice to have methods to get the current fullscreen state and set it to a specific state too.
