oauth2 VS http

oauth2

You don't yet understand the nuances of Dart, Flutter, and/or the Dart team's Oauth2 package in Dart/Flutter (https://pub.dev/packages/oauth2), and so your code is not written correctly.

For finding new packages, Flutter developers often visit https://pub.dev. Say you want to do a network request to a remote server using the http package, you can simply add it to your dependencies and then execute flutter pub get to fetch the package and make it ready to use.

For example if you want to add TTS functionality to your application, you can use an already existing package for it. If you want to submit POST/GET requests to an API, you can use the http package to add this.

But http package still lacks some features. Recently, the package was updated to 1.0.0. But being able to abort requests is still not supported by the http package. Plus, the package is just a wrapper around the HTTP implementation in dart:io and dart:html

There's also this package which adds the missing cancellation support, an issue open for 2 years.

http

Im using: Flutter with the dart http package;

http: It will be necessary to download the image in the temporary directory.

Add the HTTP package and getx package in pubspec.yaml.

The http package is part of Dart and has everything you need to request any remote server you want, no need to specifically be firebase or supabase. It's a bit low level so you might want to use other packages that make the task of consuming remote services easier.
