Development

To develop and locally test Pangolin:

Step 1. Install development tools

1. Install Flutter
2. Install an IDE of your choice (we recommend VSCode)
   • We also recommend installing Dart and Flutter extensions if you're opting in for VSCode. For other IDEs, please inform yourself.

Step 2. Run Pangolin

Note: You can run Pangolin on any platform that Flutter supports but we recommend running it on Linux as some features of Pangolin are designed exclusively for Linux and won't work on other platforms.

Run Pangolin by running:

make run target=linux

List of targets:

• linux
• windows
• macos

Flutter has hot reloading so no need to restart the instance when it's running!

missing binaries

In the releases are only a *.apk as binary.
But I want a system in QEmu, VMWare, VirtualBox or Android Studio which runs from Zircon over Garnet and Peridot until Topaz the complete system.

For example the Android Emulator in Android Studio bundled with the Fuchsia System, which existing as binary for MS-Windows.
Or other easy ways to try the complete system out.

Notifications & notification area

Is your feature request related to a problem? Please describe.
N/A

Describe the solution you'd like
Modern operating systems, starting with mobile systems such as Android and iOS, moving to desktop operating systems such as Windows, macOS, and Linux, and even game consoles such as the Xbox and Nintendo Switch have system notification systems. dahliaOS developers would benefit from being able to send notifications to their users.

Describe alternatives you've considered
I was considering a "user feed" that starts with notifications, then proceeds to weather, news, etc.

Additional context
There's already a non-functional "notification area" in the launcher. Perhaps we should use some sort of socket on Dahlia Linux and the native Fuchsia mechanism for Zircon.

I really like this so far, however...

Is your feature request related to a problem? Please describe.
Maybe. The default applications do not match the theme of the system and settings app.

Describe the solution you'd like
Instead of shipping apps like it's an Android app, (because the calculator app looks like an app meant for android in case of usability and ux), make a universal theme for the apps based on the settings app and tge system theme.

Describe alternatives you've considered
No alternatives that I considered so far

For which platform is this feature request?

• Platform: Linux, Desktop

Do you have an idea of how we would add it?
No.

Why should we add it?
It would boost user experience, and would make DahliaOS the best Linux OS the world has seen

Additional context

[BUG] No interaction on web demo

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Opening the web demo, only the basic layout and the initial dialog seem to work. Trying to open the start menu, or interact with any of the UI seems to not work.

Expected behavior

Clicking on the start/search and other widgets should open up their menus to demonstrate their behavior. Internal settings apps etc. should be able to be opened to demonstrate pangolin's layout and window management.

Steps to reproduce

1. Go to web.dahliaos.io
2. Try to interact with the interface after closing the initial "this is alpha" dialog.

Environment (values that do not apply assign with "N/A")

- Browser: Tried on Firefox 115 and Chromium 115

This project is brilliant! I'd love to give it a spin on real hardware at some point and contribute <3

Test Issue

Testing Discord Integration

Migrate theme settings to the same API we use for localization

Currently, we use the shared preferences plugin through Norbert Koszir's dynamic_theme package, It would be very nice to actually have global color theming, with more colors than red and blue, since his plugin is a bit limited.

I would like use to migrate theme to Hive, and have the global theme color changed between all of the material colors, when the theme button is pressed.

Expected screenshot in readme :(

Report a bug/Feature request application

Is your feature request related to a problem? Please describe.
It is related to all future bug reports/feature requests

A simple app written in Flutter that would offer the user to either report a bug or request a feature/make a suggestion and would provide fields which the user would have to fill in, after his report/request is done, the app would forward it to here, GitHub issues.

Because pangolin depends on flutter_localizations from sdk which depends on intl 0.17.0, intl 0.17.0 is required.

Warning: implicit declaration of function 'waitpid' is invalid in C99

The following error occurs when building on Linux.

pangolin_desktop/linux/flutter/ephemeral/.plugin_symlinks/flutter_pty/src/flutter_pty_unix.c:94:5: warning: implicit declaration of function 'waitpid' is invalid in C99 [-Wimplicit-function-declaration]

But for the record I am building on WSL2 so I'm not sure if it's to do with that, and I used flutter build linux.

Action Center/Quick Settings overlapping.

So this has been happening for a little bit and I thought it was just the web, until I tried it on windows. This happens on all my platforms, android, windows, and web, at this point it was just annoying to me.


There's some screenshots so you can hopefully fix it! Thanks! <3

Not able to run dahliaOS on VirtualBox

Describe the bug
Yesterday i wanted to try out dahliaOS so I downloaded the legacy version to test it out in VirtualBox and after setting everything up when I tried to run the Machine it ran the initial screen and then it was stuck on the initial screen and in noticed my CapsLock light on keyboard started blinking and it never booted into dahliaOS.

What kind of a bug is it?
It is an OS Bug which is not letting me run dahliaOS on VirtualBox

To Reproduce
Steps to reproduce the behavior:

1. download the latest legacy version
2. Setup virtual box with recommended amount of resources
3. Try to start the Virtual Machine
4. See error

Expected behavior
During the initial boot itself you will never make it into the system and it will just stay on a black screen with text and CapsLock light will start blinking

Screenshots

dahliaOS build version

Battery mode is shown before the current battery % is loaded.

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Opening the quick settings overlay shows the battery tile initially show the the battery performance mode only to be replaced by the battery percentage after the future has loaded. This looks a little jarring.

simplescreenrecorder-2023-06-10_05.36.44.mp4

Expected behavior

Show the percentage from the start. One way to do this would be to load the future when the desktop starts up and collect that value. Might wanna use streams to continuously update the value as well.

Move apps out of this repo and figure out a way to load them

Make independent repos for all applications and figure out a way to load them from outside

Running on MAC and Windows

Can someone let me know if this is useful.

I was curious what the UX experience is to run it on a Desktop.
Its actually very useful, because you can run it in full screen, and just use the apps and forget about the real desktop behind it.

also its quick for working on the app because go-flutter has hot reload.

I only had to make minor mods to the main.dart file and add a main_desktop.dart file and break out the "MyApp" class to a new file called mainapp.dart, and get the new main.dart and main_desktop.dart to call it.

[BUG] DahOS-Desktop not work's for any linux

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

i built it with flutter, but because of an unknown problem, DE does not appear, and instead this shows flutter demos, I tried on openbox, problems gtk it's gone, but the Flutter demos problem still exists, but 2022 DE, It even works with GNOME

Did I forget something or is it a source code problem.

Expected behavior

Put your feelings aside, ok my friend :)

The important thing is that I expect from the source code because I tried it on 3 distributions with the same steps

Nix
Arch
Fedora

They all have the same problem, I tried modifying ./linux/my_application.cc and no results.

Improve performance of Icon rendering in `CompactLaucherOverlay`

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

Scrolling through the listview leads to icons taking some time before actually getting rendered. I haven't looked closely at the source code but I'm sure there must be a way to improve things here. Maybe caching the path the icon is located at? Will take a deeper look.
