Xournal++ Mobile App Built with Flutter

Xournal++ Mobile

Warning: Xournal++ Mobile is currently in early development and not yet stable. Use with caution!

A port of the main features of Xournal++ to various Flutter platforms like Android, iOS and the Web.

Try it out

Mission completed: We can now render strokes, images and text and LaTeX!. We thereby support the full .xopp file format. ?

sudo snap install xournalpp-mobile

Known issues

  • Immense memory consumption: If you open immense files, you get immense memory consumption. That’s logic. Usually, Xournal++ Mobile takes twice the file size plus around 50MB for itself.
  • But why does it take twice the memory?: No idea. ¯\_(ツ)_/¯
  • The snap does not start on Linux when using wayland: Please set the environment variable DISABLE_WAYLAND=1 before you start Xournal++ Mobile.

Test for the web

If you want to test for the web, please run:

flutter channel beta
flutter upgrade
flutter config --enable-web
flutter run -d web --release --no-sound-null-safety # unfortunately, the debug flavour will result an empty screen

Desktop support

Linux is perfectly supported by Xournal++ Mobile and you can get prebuilt binaries above or install from Snap Store.

Windows is supported and tested too, but there are unfortunately no prebuilt binaries available. Execute the following commands to build them yourself.

If you want to test for Linux, Windows or macOS, please run:

flutter channel master
flutter upgrade
flutter config --enable-linux-desktop # or --enable-macos-desktop or --enable-windows-desktop
flutter run -d linux --no-sound-null-safety # or macos or windows
