# join method Null safety

String join (

1. [String separator = ""]

)
inherited

Converts each element to a String and concatenates the strings.

Iterates through elements of this iterable, converts each one to a String by calling Object.toString, and then concatenates the strings, with the `separator` string interleaved between the elements.

## Implementation

    String join([String separator = ""]) => readClasses().join(separator);
