Can I use http_interceptor in flutter web?

[mmadtop]

Hello, I've succesfully used this library for a mobile app. I'm trying to use it in a web app but it gives me error when I make a request with interceptor.

I would like to know if is not provided for the web version or if is another type of error.

Thank you in advance.

this is the stack:

Hi, short answer: currently no.

Long answer: I am working on it. Since Flutter Web is not stable yet it can change and it's not part of what I initially thought to implement. However, my plan for this is to add a separate branch that provides support for this, especially since this is really a simple plugin that should be allowed to be used in different platforms even while in beta.

Can you please keep this one open? Even though it's not stable yet, there are a lot of people using it already. And having this package work on web would be great.

[CodingAleCR]

Sure thing. Still on my to-do though

Sure thing. Still on my to-do though

what's the crux of the issue? I set breakpoints and this is where the error is throwing: https://github.com/CodingAleCR/http_interceptor/blob/94cfcaeb6010174621f2da40b825c10ce2740386/lib/http_client_with_interceptor.dart#L49-L54

[CodingAleCR]

TBH, I didn't expect the plugin to be used much besides by myself, but I'm noticing an increase in the usage, so I'm moving this up in my priorities so that I can give proper maintenance to the plugin and provide usefulness out of it for the whole flutter community. So sorry it has taken this long 😔

[CodingAleCR]

As of 0.4.0 you should be able to use this plugin for flutter web without any issues. Cheers!
