Variables ✨

Outputs 📦

--exception_name custom
── custom_exception.dart
── custom_exception.freezed.dart

import 'package:freezed_annotation/freezed_annotation.dart';

part 'custom_exception.freezed.dart';

@freezed
class CustomException with _$CustomException implements Exception {
  const factory CustomException.otherError({
    required Object error,
    required StackTrace stacktrace,
  }) = _OtherError;
  
  const factory CustomException.networkError({
    @Default('NetworkError') String? message,
  }) = _NetworkError;
  
  const factory CustomException.unauthorizedError({
    @Default('UnauthorizedError') String? message,
  }) = _UnauthorizedError;
  
}

After you use it inside a repo or service you can handle all possible errors like this

void main(){
   try{
      yourRepoOrService.fetchSomeData();
   } on CustomException catch (e){
      e.when(
        networkError:(message)=>//handle this.
        unauthenticated:(message)=>//handle this.
        otherError:(error,stacktrace)=>//handle this.
      );
   }
}
