const isFlexItem = child && child.type && ((child.type as any) as typeof FlexItem).__isFlexItem
// or
const isFlexItem: boolean = _.get(child, 'type.__isFlexItem')

Do we need a condition there?
Without it we will get:
<>
{null}
{null}
</>But it will not affect the markup

Nevermind,
If children is null or undefined, this method will return null or undefined rather than an array.

yes - but, essentially, we won't like to draw anything if falsy value is provided - and this is exactly the effect logic provides. Thus I would rather leave it the way it is now - as a benefit this won't introduce any additional React elements to output elements tree
