> 
> **Overview**
> **Release 4.19.0** for `launchdarkly_flutter_client_sdk`: bumps the
package version from **4.18.1** to **4.19.0** in `pubspec.yaml`, the
embedded `sdkVersion` in `ld_client.dart`, the example app dependency,
and `.release-please-manifest.json`.
> 
> The changelog documents the user-facing change shipped in this
release: **debouncing** of lifecycle, network, and `setMode` signals
before `ConnectionManager` runs automatic connection-mode resolution
(default **1s** window via `debounceWindow`; `offline` still applies
immediately without debounce).
