v1.2.19

• FunctionArgs0Extension, FunctionArgs1Extension, FunctionArgs2Extension:

  • tryCall: updated to catch errors from synchronous or asynchronous results and apply onError via Future.catchError if the result is a Future.

• ComputeOnce<V>:

  • Constructor:
    • Added static helper _resolveCall to widen callbacks returning Future<Never> to FutureOr<V>.
    • Wrap _call with _resolveCall to fix Future<Never> callbacks.
  • Added isResolving getter to indicate if computation is in progress.
  • Enhanced resolve method:
    • Added parameters throwError, onError, and onErrorValue to control error handling behavior.
    • Supports returning fallback values or invoking error handlers instead of always throwing.
    • Calls onCompute callback on completion with value or error.
  • Enhanced resolveAsync method:
    • Added parameters throwError, onError, and onErrorValue for asynchronous error handling.
    • Calls onCompute callback on completion.
  • Added onCompute callback method invoked once computation completes.
  • Added className getter and improved toString to reflect current state (resolving, resolved with value, or error).

• Added TimedComputeOnce<V> subclass:

  • Records the timestamp when computation resolves (success or failure).
  • Provides resolvedAt timestamp and elapsedTime since resolution.
  • Overrides onCompute to set resolution time.
  • Overrides className for identification.
