openWrite method

@override StreamSink<List<int>> openWrite({ FileMode mode = FileMode.write, Encoding encoding = utf8, })

Creates a new independent StreamSink for the file. The StreamSink must be closed when no longer used, to free system resources.

An StreamSink for a file can be opened in two modes:

• FileMode.WRITE: truncates the file to length zero.
• FileMode.APPEND: sets the initial write position to the end of the file.

When writing strings through the returned StreamSink the encoding specified using encoding will be used. The returned StreamSink has an encoding property which can be changed after the StreamSink has been created.

Implementation

@override
StreamSink<List<int>> openWrite(
        {FileMode mode = FileMode.write, Encoding encoding = utf8}) =>
    throw UnsupportedError('file.openWrite');
