operator == method

  1. @override
bool operator ==(
  1. Object other
)

The equality operator.

The default behavior for all Objects is to return true if and only if this object and other are the same object.

Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:

  • Total: It must return a boolean for all arguments. It should never throw.

  • Reflexive: For all objects o, o == o must be true.

  • Symmetric: For all objects o1 and o2, o1 == o2 and o2 == o1 must either both be true, or both be false.

  • Transitive: For all objects o1, o2, and o3, if o1 == o2 and o2 == o3 are true, then o1 == o3 must be true.

The method should also be consistent over time, so whether two objects are equal should only change if at least one of the objects was modified.

If a subclass overrides the equality operator, it should override the hashCode method as well to maintain consistency.

Implementation

@override
bool operator ==(Object other) {
  if (identical(this, other)) return true;
  if (other is! SDKOptions) return false;
  SDKOptions _other = other;
  return scope == _other.scope &&
      cachePath == _other.cachePath &&
      cacheSizeInBytes == _other.cacheSizeInBytes &&
      dataPath == _other.dataPath &&
      persistentMapStoragePath == _other.persistentMapStoragePath &&
      politicalView == _other.politicalView &&
      offlineMode == _other.offlineMode &&
      layerConfiguration == _other.layerConfiguration &&
      DeepCollectionEquality().equals(catalogConfigurations, _other.catalogConfigurations) &&
      autoUpdateOfOnlineCache == _other.autoUpdateOfOnlineCache &&
      DeepCollectionEquality().equals(customEngineOptions, _other.customEngineOptions) &&
      actionOnCacheLock == _other.actionOnCacheLock &&
      authenticationMode == _other.authenticationMode &&
      networkSettings == _other.networkSettings &&
      lowMemoryMode == _other.lowMemoryMode &&
      billingTag == _other.billingTag &&
      customOptions == _other.customOptions;
