I get a black screen when attempting to sign in via sso in my flutter app

I am calling the authorize method of the flutter_appAuth package on android.

Here is what that method looks like:

final result = await FlutterAppAuth().authorize(
    AuthorizationRequest(
      SSOConstants.clientId,
      SSOConstants.redirectUri,
      serviceConfiguration: AuthorizationServiceConfiguration(
        authorizationEndpoint: SSOConstants.authorizationEndpoint,
        tokenEndpoint: SSOConstants.tokenEndpoint,
      ),
      scopes: SSOConstants.scopes.split(' '),
    ),
  );

After I call the authorize method, I get redirected to ‘login.microsoftonline.com’ and I either get a black screen or a glitchy screen. It seems to just hang there after it is done loading. I get no error returned or no feedback about what went wrong.

Here is what the screen shows:

Here is my build.gradle line:

    manifestPlaceholders = [
        'appAuthRedirectScheme': 'msauth' 
    ]

The format of my uri is:

msauth://com.example.test/1234

I do not get back any errors. There is no exception. All I get is this in the debug console:

I am trying to sign in with SSO on my mobile app in local host, but I just get a black or glitched screen when attempting to sign in instead of the account picker or microsoft sign in dialogue. Also, iOS works fine.
