copyUpdateOnThen<A2> method

ContObserver<F, A2> copyUpdateOnThen<A2>(void onThen(A2 value))

Returns a copy of this observer with a replaced onThen callback and a new value type A2.

• onThen: The new then callback.

Implementation

ContObserver<F, A2> copyUpdateOnThen<A2>(
  void Function(A2 value) onThen,
) {
  return switch (this) {
    SafeObserver<F, A>(
      isUsed: final isUsed,
      _onUnsafePanic: final _onUnsafePanic,
      onElse: final onElse,
      onCrash: final onCrash,
    ) =>
      SafeObserver._(
        isUsed,
        _onUnsafePanic,
        onCrash,
        onElse,
        onThen,
      ),
    _UnsafeObserver<F, A>(
      _onUnsafePanic: final _onUnsafePanic,
      onElse: final onElse,
      onCrash: final onCrash,
    ) =>
      _UnsafeObserver._(
        _onUnsafePanic,
        onCrash,
        onElse,
        onThen,
