| * @assertion Future<File> writeAsString( |
| * String contents, { |
| * FileMode mode: FileMode.write, |
| * Encoding encoding: utf8, |
| * bool flush: false |
| * }) |
| * Write a string to a file. |
| * |
| * Opens the file, writes the string in the given encoding, and closes the file. |
| * Returns a Future<File> that completes with this File object once the entire |
| * operation has completed. |
| * |
| * By default writeAsString 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. |
| * @description Checks that this method writes a string to a file in a utf8 |
| * encoding |
