deduplicateProviders method

List<ProviderElement> deduplicateProviders(Iterable<ProviderElement> providers)

Returns a unique ordered-set based off of providers.

ProviderElement.token is used to determine uniqueness.

Implementation

List<ProviderElement> deduplicateProviders(
  Iterable<ProviderElement> providers,
) {
  final soloProviders = LinkedHashSet<ProviderElement>(
    equals: (a, b) => a.token == b.token,
    hashCode: (e) => e.token.hashCode,
    isValidKey: (e) => e is ProviderElement,
  )..addAll(providers.where((e) => !e.isMulti).toList().reversed);
  return soloProviders.toList()..addAll(providers.where((e) => e.isMulti));
}
