whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String userId,
    2. String provider,
    3. String? apiKey,
    4. String? model,
    5. String authMode,
    6. String? oauthTokenId,
    7. DateTime? updatedAt,
    )?
)

A variant of when that fallback to returning null

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function(@JsonKey(name: 'user_id')  String userId,  String provider, @JsonKey(name: 'api_key')  String? apiKey,  String? model, @JsonKey(name: 'auth_mode')  String authMode, @JsonKey(name: 'oauth_token_id')  String? oauthTokenId, @JsonKey(name: 'updated_at')  DateTime? updatedAt)?  $default,) {final _that = this;
switch (_that) {
case _UserAiSettingsModel() when $default != null:
return $default(_that.userId,_that.provider,_that.apiKey,_that.model,_that.authMode,_that.oauthTokenId,_that.updatedAt);case _:
  return null;

}
}
