onError method

@override void onError(DioError err, ErrorInterceptorHandler handler)

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) async {
  var box = await getBox<CallCacheModel>('calls');
  var model = box.get(box.values.toList().length);
  if (model != null) {
    var type = err.type;
    await box.put(
        box.values.toList().length,
        model.copyWith(
            eventMessage: err.stackTrace.toString(),
            statusCode: type == DioErrorType.other
                ? "-1"
                : err.response?.statusCode.toString(),
            response: err.response?.data.toString()));
  }
  super.onError(err, handler);
}
