The method '+' was called on null

[Holofox]

Hello! Thanks for the package! There is a problem with form data requests.

NoSuchMethodError: The method '+' was called on null.\nReceiver: null\nTried calling: +("Form data")]

I'm guessing the problem is on this line:

infospect/lib/features/network/interceptors/infospect_dio_interceptor.dart

Line 51 in 157e004

body += "Form data";

I also think it’s worth wrapping all the handlers in the interceptor in try/catch, so that in case of an error this does not affect the sending of the request. The error can be made non-blocking via handler.next() so that other interceptors can continue working.

infospect/lib/features/network/interceptors/infospect_dio_interceptor.dart

Line 39 in 157e004

void onRequest(RequestOptions options, RequestInterceptorHandler handler) {

infospect/lib/features/network/interceptors/infospect_dio_interceptor.dart

Line 111 in 157e004

void onResponse(Response response, ResponseInterceptorHandler handler) {

infospect/lib/features/network/interceptors/infospect_dio_interceptor.dart

Line 145 in 157e004

void onError(DioException error, ErrorInterceptorHandler handler) {

Hey @Holofox , Thanks for pointing this out,
the body param is not yet initialized and +("Form data") was being appended to it.

Will fix this and let you know and I agree to your suggestion to handle the interceptors with try/catch, so that it wont hamper the Call, if the interception failed.

@Holofox , The fix has been added in 0.1.2.
