FAQPage Schema
How do I set up a global error handler for Flutter apps to centralize error logging?▼

Set up a global error handler for Flutter apps by assigning a function to Superpowers.globalCatchError in main() before runApp(). This routes all unhandled mix() call errors to a single handler for logging and standardization.

What is the best way to catch unhandled errors from mix() calls in Flutter?▼

The best way to catch unhandled errors from mix() calls is configuring Superpowers.globalCatchError. This intercepts all mix() errors globally, allowing you to log stack traces and convert them to user-friendly messages.

Can I show a user-friendly dialog when a global error occurs in Flutter?▼

Yes, you can show a user-friendly dialog by routing errors through UserException in your global error handler. This strategy converts internal errors into readable dialogs for users.

Does centralizing error handling in Flutter support crashing in debug mode?▼

Yes, centralizing error handling supports crashing in debug mode. The handler provides three strategies: suppressing errors, showing a dialog via UserException, or crashing during debug.

Why do I need to define error and stackTrace parameters for a Flutter global catch handler?▼

Defining error and stackTrace parameters is required to process and log the caught exceptions accurately. These parameters enable the handler to execute logging, analytics, and error conversion properly.
