Authentication error when receive redirect from acquireToken

[ductranit]

I tried to follow the document & an example in this plugin. User can sign in in b2c but it always in the redirect step with the exception Authentication error.
My redirect url: msauth.com.my.package://auth
I also set the CFBundleURLTypes & LSApplicationQueriesSchemes like the document & example, but still doesn't work.
My code:

Future<String> acquireToken() async {
    if (pca == null) {
      pca = await PublicClientApplication.createPublicClientApplication(
          _clientId,
          authority: _authority);
    }
    try{
    await pca.logout();
    } on MsalException catch(e){
        LogUtil.e(e);
    }

    try {
      return await pca.acquireToken([
        "https://mytenant.onmicrosoft.com/b2capi/user_impersonation"
      ]);
    } on MsalUserCancelledException catch(e) {
      LogUtil.e(e);
    } on MsalNoAccountException catch(e){
      LogUtil.e(e);
    } on MsalInvalidConfigurationException catch(e){
      LogUtil.e(e);
    } on MsalInvalidScopeException catch(e){
      LogUtil.e(e);
    } on MsalChangedClientIdException catch(e){
      LogUtil.e(e);
    }on MsalUninitializedException catch(e){
      LogUtil.e(e);
    }on MsalInitializationException catch(e){
      LogUtil.e(e);
    } on MsalException catch(e){
      LogUtil.e(e);
    }
  }

Do you have any idea to debug the detail problem?

@ductranit sorry forgot to reply sooner. Do you get any errors in the log output? Also which version of iOS and please confirm if your xcode and flutter are all updated and using the latest versions.

Hi, I'm having also this same issue on iOS. It doesn't show a webpage, it immediately throws an exception when acquiring token.

I've already add the required items inInfo.plist

<key>CFBundleURLTypes</key>
<array>
	<dict>
		<key>CFBundleURLSchemes</key>
		<array>
			<string>msauth.com.mycompany.sample</string>
		</array>
	</dict>
</array>
<key>LSApplicationQueriesSchemes</key>
<array>
	<string>msauthv2</string>
	<string>msauthv3</string>
</array>

I've already changed the deployment target to iOS 11 for both project and the added this platform :ios, '11.0' in the Podfile.

Running on iPhone 8+ (iOS 12), Xcode 11.3.1, Flutter 1.12.13+hotfix8

Sorry I didn't get github email notification until now. I'm not working on this project now.
I decided to use the webview to show custom b2c authentication website instead of this library.

Does anyone know about a solution?

Hi @eladcandroid, sorry about the delay in getting back, just realised i actually didnt have notifications properly set up, which is why i kept missing so many >_<
For the time being, unfortunately i'm a bit short on time, however I have a rather extensive rewrite planned so unfortuantely it will have to wait until this. I'll try to get started on it soon
