Hi Andy, welcome aboard. Before I began using FF, I had limited coding knowledge too. Here are some tips that might help you:

Start by downloading a pre-made template from the marketplace (or from FF by clicking the 'create new project' button). Try to comprehend its structure and purpose. Then, attempt to replicate it by copying and pasting the solutions. This will help you understand how FF operates and how to use it.
If you're working on something unfamiliar, always refer to the documentation and directly copy the solution.
Check out the official Flutterflow YouTube channel. Short tutorials are available to help you understand the features, and lengthy live recordings can guide you on how to build a product.
I also recommend other YouTubers like James NoCode and Dimitar Klaturov. Or simply search 'Flutterflow' on YouTube to find more resources.
Understand how to manage data. Firebase uses NoSQL and Supabase uses Postgres. Take the time to comprehend these database structures and their differences. It might be challenging initially, but it will be beneficial in your app development journey.
Learn about JSON and how APIs work.
The community has answered many questions. Search for solutions if you're stuck.
Use ChatGPT to generate custom codes for you or explain a concept (for example, the difference between Firebase and Supabase).
Acquire some basic UI+UX knowledge. There are numerous courses available to help you understand what makes an app attractive and user-friendly. Alternatively, you can purchase a UI template from UpLabs or similar sites and replicate it.

I think, if you invest time and effort into these tips, you can create any app.
