onError method
The callback will be executed on error.
If you want to continue the error , call handler.next
.
If you want to complete the response with some custom data directly,
you can resolve a Response
object with handler.resolve
and other
error interceptor(s) will be skipped.
If you want to complete the response with an error message directly,
you can reject a DioError
object with handler.reject
, and other
error interceptor(s) will be skipped.
Implementation
@override
void onError(DioError err, ErrorInterceptorHandler handler) {
// ignore: avoid_print
print(
'ERROR[CODE] => PATH: ${err.response?.statusCode}',
);
// ignore: avoid_print
print(
'ERROR[RESPONSE BODY] => RESPONSE FROM SERVER: ${err.response!.data.toString()}',
);
return super.onError(err, handler);
}
