# every method Null safety

bool every (

1. bool test(
   1. E element
   )

)
inherited

Checks whether every element of this iterable satisfies `test`.

Checks every element in iteration order, and returns `false` if any of them make `test` return `false`, otherwise returns `true`.

## Implementation

    bool every(bool test(E element)) {
      int length = this.length;
      for (int i = 0; i < length; i++) {
        if (!test(elementAt(i))) return false;
        if (length != this.length) {
          throw new ConcurrentModificationError(this);
        }
      }
      return true;
    }
