add(T data, {bool skipIfClosed = false, bool skipSame = false, bool skipNull = false}) → bool: Push data to the stream. Ignored if skipIfClosed is true and the stream is closed. Ignored if skipSame is true and data == value. Ignored if skipNull is true and data is null. Return true if value was added.
