# writeAll method Null safety

void writeAll (

1. Iterable objects,
2. [String separator = ""]

)
override

Iterates over the given `objects` and writes them in sequence.

If `separator` is provided, a `write` with the `separator` is performed between any two elements of objects.

This operation is non-blocking. See flush or done for how to get any errors generated by this call.

## Implementation

    void writeAll(Iterable objects, [String separator = ""]);
