# unordered abstract method

S unordered()

Returns an equivalent stream that is unordered.

May return itself, either because the stream was already unordered, or because the underlying stream state was modified to be unordered.

This is an intermediate operation.

## Example

    final stream = DartStream.of([1, 2, 3, 4, 5]);
    final unorderedStream = stream.unordered();
    // Order is no longer guaranteed in parallel operations

## Implementation

    S unordered();
