I’m working on integrating Binance OAuth authentication into my Flutter application but encountering a configuration issue

const String discoveryURL = 'https://accounts.binance.com/.well-known/openid-configuration';
const String binanceAuthorizationUrl = 'https://accounts.binance.com/oauth/authorize';
const String binanceTokenUrl = 'https://accounts.binance.com/oauth/token';
const String binanceIssuer = 'https://accounts.binance.com';

final List<String> scopeList = [
    "user:openId"
  ];

final AuthorizationTokenResponse? result = await appAuth.authorizeAndExchangeCode(
      AuthorizationTokenRequest(
        dotenv.env['BINANCE_CLIENT_ID']!,
        dotenv.env['BINANCE_REDIRECT_URI']!,
        clientSecret: dotenv.env['BINANCE_CLIENT_SECRET']!,
        serviceConfiguration: AuthorizationServiceConfiguration(
          authorizationEndpoint: binanceAuthorizationUrl,
          tokenEndpoint: binanceTokenUrl
        ),
        discoveryUrl: discoveryURL,
        scopes: scopeList,
        issuer: binanceIssuer,
        nonce: 'nonce',
      ),
    );

Here is the error

login error: PlatformException(authorize_and_exchange_code_failed, Failed to authorize: [error: invalid_client, description: null], null, null)

I tried to change client secrets but still get same issue and I expect to get access token
