# whereType<T> method Null safety

Iterable<T> whereType <T>()
override

Returns a new lazy Iterable with all elements that have type `T`.

The matching elements have the same order in the returned iterable as they have in iterator.

This method returns a view of the mapped elements. Iterating will not cache results, and thus iterating multiple times over the returned Iterable may yield different results, if the underlying elements change between iterations.

## Implementation

    Iterable<T> whereType<T>() => WhereTypeIterable<T>(this);
