application closing when authentication tab ends

[pankokmu1]

It opens the authentication tab, returns to the application and when it goes to get the token it gives an error due to a comparison that it tries to do with a null value

final authorize = await appAuth.authorize(
        AuthorizationRequest(
          sso.clientId,
          'com.example.app://oauth2',
          issuer: sso.issuer,
          scopes: sso.scopes,
          promptValues: sso.prompt,
          loginHint: sso.loginHint,
          allowInsecureConnections: true,
          additionalParameters: sso.parameters,
        ),
      );

final result = await appAuth.token(
        TokenRequest(
          sso.clientId,
          'com.example.app://oauth2',
          allowInsecureConnections: true,
          authorizationCode: authorize.authorizationCode,
          issuer: sso.issuer,
          codeVerifier: authorize.codeVerifier,
        ),
      );

@pankokmu1 do you know what the login hint here is? is it the actual email of the user, or the actual user name?

or is it perhaps the the input TYPE from html? or perhaps the input AUTOCOMPLETE value from html?

How did you fix this?
