I tried to copy ~/flutter/bin/cache/artifacts/engine/linux-arm64-release/gen_snapshot to~/flutter/bin/cache/artifacts/engine/android-arm64-release/linux-arm64/gen_snapshot but this didn't work. Building flutter apk on arm64 Linux require specific android/gen_snapshot for compiling apk in release mode. I don't know how but compiling apk in debug mode work on arm64 Linux.
