[Windows] windowManager.close() does not close the window

[edeuss]

For some reason, windowManager.close() does not close the window for my flutter project. I downloaded your example, and it works fine there, but is there any reason that something might cause it not to work?

Quit on close If you need to use the hide method, you need to disable QuitOnClose.

macOS Change the file macos/Runner/AppDelegate.swift as follows:

import Cocoa
import FlutterMacOS

@NSApplicationMain
class AppDelegate: FlutterAppDelegate {
  override func applicationShouldTerminateAfterLastWindowClosed(_ sender: NSApplication) -> Bool {
-    return true
+    return false
  }
}

Did you follow this?

@JasCodes This is not for macOS, macOS closes fine; it is just Windows. I am not 100% sure the issue is this package, it throws no errors so I am having a hard time troubleshooting it.

How to disable the QuitOnClose?

[milindgoel15]

Hello, I was also experiencing this issue until I found that you need to add listener for windowManager in the initstate and also add a dispose method. So check your code for it.

你好，有人知道如何在Linux上禁用QuitOnClose吗

[lijy91]

On windows make sure you set quitOnCloase to true.

windows/runner/main.cpp

window.SetQuitOnClose(true);

and you don't prevent the close in your dart code

void _init() async {
    // Must not be set to true
    // await windowManager.setPreventClose(true);
    setState(() {});
  }
