auth0-blog / flutter-authentication Goto Github PK

Downloaded latest github repo, setup Auth0 account. Login -> Flutter app just spins and never completes. I believe an error is occurring within getUserDetails method.

I tried logging in, and it spins forever.

Now Flutter have desktop support on stable version.

Is possible to use auth0 with flutter on desktop application?

Can you please add a licence to this project?

Attribute application@name at AndroidManifest.xml:5:9-42 requires a placeholder substitution but no value for is provided.

My Environment

~/S/s ❯❯❯ flutter --version
Flutter 2.5.3 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 18116933e7 (3 weeks ago) • 2021-10-15 10:46:35 -0700
Engine • revision d3ea636dc5
Tools • Dart 2.14.4

Cause

Because the published code is not null-safe.

Provisional support #1 Disable null safety

Change pubspec.yaml as follows

environment:
  sdk: ">=2.7.0 <3.0.0"

Provisional support #2 Parse the url

    const String url = 'https://$AUTH0_DOMAIN/userinfo';
    final http.Response response = await http.get(
      Uri.parse(url),
      headers: <String, String>{'Authorization': 'Bearer $accessToken'},
    );

I was able to confirm that it works, but it would be nice if the code to make it work null-safely is available.

Hello!
I am developing a multiplarform app in Flutter. I already have my auth0 login working with the base package in mobile, but since that package doesn't support web I'm looking for a package that does. When I tried yours, i get this error when using : Auth0Flutter2.instance.loginUser();

Does the package work for web? I hope i didn't do anything wrong. I did this in my initState in main:
/// Also init alternative auth0 package for web/desktop
Auth0Flutter2.auth0Domain = AUTH0_DOMAIN;
Auth0Flutter2.auth0ClientId = AUTH0_CLIENT_ID;
Auth0Flutter2.redirectUri = AUTH0_REDIRECT_URI;
Auth0Flutter2.setPathUrlStrategy();
checkForRedirectCallback();

And also added this to web\index.html (hope it's the correct place, the info is not very specific about where to add it exactly) :

Hope you can help me make it work!

Hi, great flutter demo with OAuth2 - finally found a sample that actually works! Question more than anything - how is Logout supposed to work? Right now it deletes the refresh token, but when you click Login again, it re-logs me in using previous credentials. I was expecting a logout that forces the user to sign-in again or change credentials. How do you envision that to work? Was that the intention of Logout? Maybe we need PR that does both? Or maybe that's a setting in Auth0 connections?
thanks - great demo!

Future<void> logoutAction() async {
    await secureStorage.delete(key: 'refresh_token');
    setState(() {
      isLoggedIn = false;
      isBusy = false;
    });
  }

Hi, I loved how you made simple the implementation basic with flutter, but I was wondering if it's possible to create my own login screen in flutter and use it to do the authentication via SDK as firebase does.

I'm following README.md but I'm getting this error when I want to sign up a new user.
