Exceptions
Exceptions are unexpected faulty behaviors that occur during the app execution. All errors and exceptions in Android or iOS apps built on Flutter SDK are handled by enumerations called ZCatalystException, defined in the Android SDK package.
If an exception occurs in your mobile app, the following Dart properties of the exception are returned:
- code: Unique identifier of the error
- errorMsg: General description about the error
- errorDetails: Additional information about the error
- originalException: The actual exception that was thrown
A list of common error codes thrown by the Catalyst Flutter SDK and their descriptions are given below:
