followedBy method
Returns the lazy concatenation of this iterable and other
.
The returned iterable will provide the same elements as this iterable,
and, after that, the elements of other
, in the same order as in the
original iterables.
Implementation
S followedBy(Iterable<T> other,
[TotalCountResolver totalCountResolver = _defaultResolver]) {
var oldLength = state.items.length;
var newData = state.items.followedBy(other);
return state.copyWith(
items: newData,
totalCount:
totalCountResolver(state.totalCount, diff(oldLength, newData.length)),
);
}
