Write a list of bytes to a file.
Opens the file, writes the list of bytes to it, and closes the file. Returns a Future<File>
that completes with this File object once the entire operation has completed.
By default writeAsBytes creates the file for writing and truncates the file if it already exists. In order to append the bytes to an existing file, pass FileMode.append as the optional mode parameter.
If the argument flush
is set to true
, the data written will be flushed to the file system before the returned future completes.
Future<File> writeAsBytes(List<int> bytes, {FileMode mode: FileMode.write, bool flush: false});
