ilkersevim_async_lifecycle 0.1.3

Avoid double completion and StreamController add-after-close errors with reusable, dependency-free Dart lifecycle helpers.

ilkersevim_async_lifecycle

Completer helpers and safe StreamController lifecycle utilities for Dart async code. Dependency-free beyond the Dart SDK (dart:async).

Why use this package?

• Centralize completer start, completion, error, and reset state instead of repeating nullable-completer checks.
• Avoid emitting into null or closed stream controllers during async teardown.
• Give services one small lifecycle mixin for controller creation and disposal.
