Authentication prompt (MFA) not appearing in MSAL flutter

[GDEVENDRAK]

In my flutter application, As I am using aad_oauth(https://pub.dev/packages/aad_oauth) for ADAL login and to migrate to MSAL now integrated msal_auth.

The problem I am facing is after entering username and password in Microsoft login page, authentication prompt(MFA) is not appearing, accessToken is able to get from MSAL. Please suggest a way to configuration changes required in msal_config.json and Azure portal(if any).

ADAL Redirect URL: https://appdev.auth.com/root/dashboard

MSAL Redirect URL: msauth://com.app.oneapp/*************************=

  final service = MsalAuthService.instance;

    final (created, exception) = await service.createPublicClientApplication(
      accountMode: AccountMode.single,
      authorityType: AuthorityType.aad,
      broker: Broker.msAuthenticator,
    );

    if (created) {
      final (result, exception) = await service.acquireToken(
        prompt: Prompt.login,
        loginHint: "",
      );

My msal_config.json configuration is

{ "authorities": [ { "type": "AAD", "audience": { "type": "AzureADMyOrg", "tenant_id": "00000000-1111-2222-3333-123456789" } } ], "authorization_user_agent": "DEFAULT", "multiple_clouds_supported": false, "broker_redirect_uri_registered": true, "http": { "connect_timeout": 10000, "read_timeout": 30000 }, "logging": { "pii_enabled": false, "log_level": "WARNING", "logcat_enabled": false }, "shared_device_mode_supported": false, "account_mode": "SINGLE", }
