BREAKING CHANGE: The .stream() method now returns an ActionStream instead of a FlowStreamResponse record. ActionStream is a Stream that provides two ways to access the flow's final, non-streamed response:

• onResult: A Future that completes with the result. This is the recommended approach. It will complete with a GenkitException if the stream terminates with an error or is cancelled.
• result: A synchronous getter that should only be used after the stream is fully consumed. It will throw a GenkitException if the stream is not consumed, terminates with an error or is cancelled.

Migration: Code that previously looked like this:

final (:stream, :response) = myAction.stream(input: ...);
await for (final chunk in stream) {
  // ...
}
final finalResult = await response;

Should be updated to use onResult:

final stream = myAction.stream(input: ...);
await for (final chunk in stream) {
  // ...
}
final finalResult = await stream.onResult;
// or
final finalResult = stream.result;
