Arduino IDE 2.x Flatpak

Flatpak build of Arduino IDE 2.x.
Please report ALL issues for the IDE here (assuming you have installed the Flathub release).
For more information see: #35.

To run the app you need USB permissions, preferably, the user has to be part of the dialout group. Alternatively, add:

KERNEL=="ttyUSB[0-9]*",MODE="0666"
KERNEL=="ttyACM[0-9]*",MODE="0666"

to /etc/udev/rules.d/50-arduino.rules.

Limit filesystem access

By default, Arduino has access to your entire home directory and places .arduino dotfolders in it. See here to limit this access and prevent dotfolder cluttering.

Running from console

If you are running the application from the console (you might need to do this to view the application's log while it is being used), run it using the flatpak run command:

flatpak run cc.arduino.IDE2

Any arguments passed to the flatpak run command will be passed to the IDE i.e.

flatpak run cc.arduino.IDE2 --log-level=warn

which only displays warning or above in the log output to the console.

Adding permanent custom flags to the IDE

If you need to always start the IDE with custom arguments then the best way to do this is to use flatpak override. For example:

flatpak override --user --env=CUSTOM_IDE_FLAGS="--log-level=warn" cc.arduino.IDE2

This is also useful if you want to enable electron's (potentially experimental) wayland support:

flatpak override --user --socket=wayland cc.arduino.IDE2
flatpak override --user --env=CUSTOM_IDE_FLAGS="--enable-features=UseOzonePlatform --ozone-platform=wayland" cc.arduino.IDE2

It is important to note that if you are experiencing issues with the IDE you MUST disable any custom flags you have before submitting a bug report here or on the IDE's bug tracker as this functionality is not officially supported.
