# toggleAll abstract method

void toggleAll(

1. Iterable<String> iterable, [
2. bool? shouldAdd

])

Toggles all classes specified in `iterable` on element.

Iterate through `iterable`'s items, and add it if it is not on it, or remove it if it is. This is the Dart equivalent of jQuery's toggleClass. If `shouldAdd` is true, then we always add all the classes in `iterable` element. If `shouldAdd` is false then we always remove all the classes in `iterable` from the element.

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

## Implementation

    void toggleAll(Iterable<String> iterable, [bool? shouldAdd]);
