🔄 Using Custom Actions in FlutterFlow to Create Reusable Business Logic

Hey FlutterFlow devs! :waving_hand:

I recently discovered how powerful Custom Actions can be in FlutterFlow - not just for adding Flutter/Dart code, but for building reusable business logic across the app.

:puzzle_piece: Why I Use Custom Actions:

In one of my apps, I had to apply the same logic in multiple places - checking user role, validating input, or preparing structured data before sending to an API.

Instead of writing this logic multiple times, I created a Custom Action once and reused it across different widgets and flows.

Example:

dart

if (user.role == 'admin' && user.isActive) {
  // Navigate or show admin-only options
}

I wrapped this into a custom action like isUserAdmin() and now use it with a simple condition block anywhere in the app.

:white_check_mark: Benefits:

  • Keeps logic centralized and easier to maintain
  • Reduces duplication across workflows
  • Makes app logic more readable and modular

:speech_balloon: Open Questions for the Community:

  • What are some clever or unique Custom Actions you’ve written?
  • Do you prefer using them over Custom Functions?
  • Any performance tips when using them frequently?

Would love to hear how you’re using Custom Actions in your real-world apps.
