isNativeOauthDeepLinkReturnUri function

bool isNativeOauthDeepLinkReturnUri(String? returnUri)

true if returnUri uses a scheme other than http / https (e.g. myapp://oauth).

Recommended on mobile so the API does not redirect to a web page (onboarding / dashboard) but reopens the native app.

Implementation

bool isNativeOauthDeepLinkReturnUri(String? returnUri) {
  final u = returnUri?.trim();
  if (u == null || u.isEmpty) return false;
  try {
    final parsed = Uri.parse(u);
    final s = parsed.scheme.toLowerCase();
    return s.isNotEmpty && s != 'http' && s != 'https';
  } catch (_) {
    return false;
  }
}
