Create your own LengthAwarePaginator with Laravel from a Collection
$page = $request->input('page') ?: 1;
$total = $collection->count();
$start = ($page - 1) * $request->input('limit');
$slice = $collection->slice($start, $request->input('limit'), true);
$paginator = new LengthAwarePaginator(
$slice->all(),
$total,
$request->input('limit'),
$request->input('page') ?: null,
[
'path' => LengthAwarePaginator::resolveCurrentPath()
]
);
