maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>({
  1. TResult context(
    1. T? builder(
      1. BuildContext context
      )
    )?,
  2. TResult ref(
    1. T? builder(
      1. ProviderReader reader
      )
    )?,
  3. TResult value(
    1. T? value
    )?,
  4. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({TResult Function( T? Function(BuildContext context) builder)?  context,TResult Function( T? Function(ProviderReader reader) builder)?  ref,TResult Function( T? value)?  value,required TResult orElse(),}) {final _that = this;
switch (_that) {
case _ValueBuilderContext() when context != null:
return context(_that.builder);case _ValueBuilderRef() when ref != null:
return ref(_that.builder);case _ValueBuilderValue() when value != null:
return value(_that.value);case _:
  return orElse();

}
