build error for ARM, can't find something for `struct termiox`

[gabboraron]

Hi, I got this on Zorin OS, android studio:

Launching lib/main.dart on sdk gphone x86 64 in debug mode...
Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':flutter_libserialport:buildCMakeDebug[arm64-v8a]'.
