When building apps with FlutterFlow, picking between camelCase (like userName) and snake_case (like user_name) matters. It’s not just style—it keeps your app clean and bug-free. Here’s the quick scoop on why camelCase is best for FlutterFlow and Firebase, why snake_case fits Supabase, and how Dart handles conversions, all in a chill, human vibe.
Why CamelCase for FlutterFlow and Firebase?
FlutterFlow builds Flutter apps using Dart, which loves camelCase for variables and functions. Using camelCase in FlutterFlow keeps your code in sync with Dart’s style, making it easier to work with generated code or custom actions. For Firebase, camelCase fields (like userName) match Dart’s vibe, so your Firestore data flows smoothly into your app without extra tweaks.
Here’s the cool part: if you accidentally use snake_case in FlutterFlow (like user_name), Dart often converts it to camelCase (like userName) in the background. But don’t rely on this—it’s safer to stick with camelCase from the start to avoid confusion in custom code or debugging.
Why Snake_Case for Supabase?
Supabase runs on PostgreSQL, where snake_case is the go-to for table and column names (like user_name). This keeps your database queries clean and matches what Supabase’s Dart library expects. Using camelCase in Supabase forces you to add quotes in queries, which is a hassle.
Mixing Both? Keep It Clear
If your app uses both Firebase and Supabase, use camelCase for FlutterFlow and Firebase, and snake_case for Supabase. Jot down your naming rules in a README to avoid mix-ups. If you need to rename Supabase fields for FlutterFlow, a simple custom action can handle it.
Quick Tips
- Use camelCase for FlutterFlow and Firebase (e.g., userName).
- Use snake_case for Supabase (e.g., user_name).
- Don’t count on Dart’s snake_case-to-camelCase conversion—start with camelCase.
- Test your setup early to catch naming issues.
Stick with camelCase for FlutterFlow and Firebase to match Dart’s style, and snake_case for Supabase to fit PostgreSQL. Dart’s conversion from snake_case to camelCase is handy, but using camelCase upfront keeps things simple. Get this right, and you’ll code faster with fewer headaches.
