runSync method Null safety

ProcessResult runSync(
  1. List<Object> command,
  2. {String? workingDirectory,
  3. Map<String, String>? environment,
  4. bool includeParentEnvironment = true,
  5. bool runInShell = false,
  6. covariant Encoding? stdoutEncoding = systemEncoding,
  7. covariant Encoding? stderrEncoding = systemEncoding}
)

Starts a process and runs it to completion. This is a synchronous call and will block until the child process terminates.

The arguments are the same as for run`.

Returns a ProcessResult with the result of running the process, i.e., exit code, standard out and standard in.

Implementation

ProcessResult runSync(
  List<Object> command, {
  String? workingDirectory,
  Map<String, String>? environment,
  bool includeParentEnvironment = true,
  bool runInShell = false,
  // TODO(#64): Remove the `covariant` keyword.
  covariant Encoding? stdoutEncoding = systemEncoding,
  covariant Encoding? stderrEncoding = systemEncoding,
});
