# addAll method Null safety

void addAll (

1. Iterable<String> iterable

)
override

Add all classes specified in `iterable` to element.

add and addAll are the Dart equivalent of jQuery's addClass.

Each element of `iterable` must be a valid 'token' representing a single class, i.e. a non-empty string containing no whitespace.

## Implementation

    void addAll(Iterable<String> iterable);
