# writeAsStringSync abstract method

void writeAsStringSync(

1. String contents, {
2. FileMode mode = FileMode.write,
3. Encoding encoding = utf8,
4. bool flush = false,

})

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 conventional line endings are needed.

Throws a FileSystemException if the operation fails.

## Implementation

    void writeAsStringSync(
      String contents, {
      FileMode mode = FileMode.write,
      Encoding encoding = utf8,
      bool flush = false,
    });
