I just received my new flutter starter kit and followed the instructions to get the IDE (I've used it before with an Arduino Uno, but on a different machine, so this is all from scratch).
I managed to flash the RangeTest example, but as things didn't seem to work as intended I decided to check the output of the console. At the same time I noticed that the IDE was spamming me to install the "Arduino Due libraries" (with a small popup that'd come back every time I closed it). I eventually gave in and installed those libraries.
Now the IDE reports that it's an Due which is connected on the port (on the Tools > Ports menu), and returns an error when I try to flash my code. The lower right indicator reports "Flutter Basic" though.
I can reinstall if this is what it takes, but I usually prefer understanding issues... Can someone enlighten me?
