[aveyselbozoglu]

In my pubspec.yaml i have, environment: sdk: ">=2.17.6 <3.13.7" , webview_flutter: ^3.0.4 , aad_oauth: ^0.4.1 versions , and in my code

static final Config config = Config(
   tenant: 'c4****ce',
   clientId: '2c****a14',
   scope: 'openid profile offline_access',
   redirectUri: 'msauth://com.myapp.mobile/w******Hw%3D',
   navigatorKey: navigatorKey,
   
 );
 final AadOAuth oauth = AadOAuth(config);
  
  await oauth.login();
  await oauth.getAccessToken();
  String? token = await oauth.getIdToken();
  

after this line of code
await oauth.login(); i can login to Azure Ad and then this error appears just a little time then my login is successful.

WebPage not available the webpage at msauth://......... net : ERR_UNKNOWN_URL_SCHEME
