Flutter Linux Window Manager (FLWM)

A flutter plugin that can be used to manage windows in linux platform. The plugin's main intension is make flutter suitable for the development of shells for linux window managers (e.g: GNOME Shell).

All necessary features needed to create panels and other shell components using flutter are provided in this plugin.

Usage

fl_linux_window_manager:
  git:
    url: [e-mail]:moduluz-io/fl-linux-window-manager.git

2. Open the my_application.cc from your flutter app's linux folder
3. Import the required header files at the top of this file

#include <fl_linux_window_manager/fl_linux_window_manager_plugin.h>

4. If you want to make the initial window of the app as a wayland layer, then add the code given below just before the gtk_widget_show(GTK_WIDGET(window)); line.

FLWM::WindowManager::convertToLayer(GTK_WINDOW(window));

5. For all other property changes for the main window, create new window, etc. you can use the Dart API of this plugin.

Troubleshooting

Layer is not enabled when running in debug mode on VSCode.

If you are running VS Code as an X11 window, then the environment variable GDK_BACKEND will be set to x11. This environment variable is used by GTK to determine if it renders the window as a wayland surface or not.

To fix the problem:

• Open your main.cc file in linux folder.
• Add the below include statement

#include <stdlib.h>

• Add the code given below to change the env variable and force GTK to use wayland backend. This code must be added at the beginning of main() function.

setenv("GDK_BACKEND", "wayland", 1);
