handle method

@override Future<BloomResponse?> handle(BloomRequest request, BloomNextFunction next)

Processes the incoming request and optionally invokes next to continue the middleware pipeline.

To pass execution down the chain, await next and return its resulting BloomResponse. To short-circuit execution (e.g. authentication rejection), return a BloomResponse directly without calling next.

Implementation

@override
Future<BloomResponse?> handle(
    BloomRequest request, BloomNextFunction next) async {
  final response = await next();
  response.headers['access-control-allow-origin'] = allowOrigin;
  if (allowCredentials) {
    response.headers['access-control-allow-credentials'] = 'true';
  }
  if (request.method == 'OPTIONS') {
    response.headers['access-control-allow-methods'] = allowMethods;
    response.headers['access-control-allow-headers'] = allowHeaders;
  }
  return response;
}
