beforeResponse method

void beforeResponse(
  1. Future<void> task()
)

Registers task to finish before this request's response is written.

For writes the next request from the same client must see — a session save, above all: once the response is out, the browser may already be following its redirect.

Implementation

void beforeResponse(Future<void> Function() task) {
  (_beforeResponse ??= <Future<void> Function()>[]).add(task);
}
