runExecutableArgumentsSync function

ProcessResult runExecutableArgumentsSync(String executable, List<String> arguments, { String? workingDirectory, Map<String, String>? environment, bool includeParentEnvironment = true, bool? runInShell, Encoding? stdoutEncoding = systemEncoding, Encoding? stderrEncoding = systemEncoding, StreamSink<List<int>>? stdout, StreamSink<List<int>>? stderr, bool? verbose, bool? commandVerbose, })

if commandVerbose or verbose is true, display the command. if verbose is true, stream stdout & stdin

Compared to the async version, it is not possible to kill the spawn process nor to feed any input.
