<itemvalue="Synchronously writes a string to a file. Opens the file, writes the string in the given encoding, and closes the file. By default [writeAsStringSync] 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 [flush] argument is set to `true`, data written will be flushed to the file system before returning. This method does not transform newline characters (`"\n"`) to the platform conventional line ending (e.g. `"\r\n"` on Windows). Use [Platform.lineTerminator] to separate lines in [contents] if platform contentional line endings are needed. Throws a [FileSystemException] if the operation fails."/>
