SPFX Provision list with data

Question

I am trying to use the SharePoint Framework to provision a list with some default data, I managed to get this working using the following elements.xml and custom schema.xml. This worked no problem creating a SharePoint Add-Inn but was more difficult using the spfx, after much trial and error things are working good. Hopefully this will help someone else who is trying to get this working.

Elements.xml:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">

<Field ID="{060E50AC-E9C1-4D3C-B1F9-DE0BCAC300F6}"

        Type="Text"
        Required="FALSE"
        Group="SPFx Columns" />

This is what the list looks like after being provisioned in SharePoint:
