# writeAsBytesSync abstract method

void writeAsBytesSync(

1. List<int> bytes, {
2. FileMode mode = FileMode.write,
3. bool flush = false,

})

Synchronously writes a list of bytes to a file.

Opens the file, writes the list of bytes to it and closes the file.

By default writeAsBytesSync 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.

The elements of `bytes` should be integers in the range 0 to 255. Any integer, which is not in that range, is converted to a byte before being written. The conversion is equivalent to doing `value.toUnsigned(8)`.

If the `flush` argument is set to `true` data written will be flushed to the file system before returning.

Throws a FileSystemException if the operation fails.

## Implementation

    void writeAsBytesSync(
      List<int> bytes, {
      FileMode mode = FileMode.write,
      bool flush = false,
    });
