I am trying to read and write GPIO pins of my Tinker Board S from a flutter application with the https://pub.dev/packages/mraa plugin. On plugin initialisation app fails because libmraa.so library is not found. Do you have any suggestions?
I would root Tinker Board S with Tinker_Board-AndroidN-V14.4.0.14-20200711 in order to access directly to GPIO pin by using a shell script. I tried the following guide but id doesn't work with the used image, Do you have any suggestion?
