Anywhere Real Estate Senior Flutter Developer interview questions

I was contacted by an external recruiter about an opportunity with Anywhere.re for a Senior Flutter Developer opportunity. However, before getting an interview I was asked to complete a programming assignment that would take about a day to complete. I completed the assignment, created a private github repo for it, and told the recruiter to have them email, text, or call me to get the repository's password. No one ever contacted me, so there is no way they were able to review my code.
