For anyone comming here from a google search (like me).
Since Bootstrap v 4.1 there are flex-grow and flex-shrink utilities, as the documentation says you can use them like this:
.flex-{grow|shrink}-0
.flex-{grow|shrink}-1
.flex-sm-{grow|shrink}-0
.flex-sm-{grow|shrink}-1
Here is a little example
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.0/css/bootstrap.min.css" rel="stylesheet" />
<div class="d-flex flex-row">
<div class="d-flex flex-grow-1 text-white justify-content-center bg-danger">
Grow 1
</div>
<div class="d-flex flex-grow-0 text-white justify-content-center bg-success">
Grow 0
</div>
<div class="d-flex flex-grow-1 text-white justify-content-center bg-danger">
Grow 1
