whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String providerId,
    3. String accountId,
    4. String userId,
    5. String? accessToken,
    6. String? refreshToken,
    7. String? idToken,
    8. DateTime? accessTokenExpiresAt,
    9. DateTime? refreshTokenExpiresAt,
    10. String? scope,
    11. String? password,
    12. DateTime? createdAt,
    13. 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( String id,  String providerId,  String accountId,  String userId,  String? accessToken,  String? refreshToken,  String? idToken,  DateTime? accessTokenExpiresAt,  DateTime? refreshTokenExpiresAt,  String? scope,  String? password,  DateTime? createdAt,  DateTime? updatedAt)?  $default,) {final _that = this;
switch (_that) {
case _Account() when $default != null:
return $default(_that.id,_that.providerId,_that.accountId,_that.userId,_that.accessToken,_that.refreshToken,_that.idToken,_that.accessTokenExpiresAt,_that.refreshTokenExpiresAt,_that.scope,_that.password,_that.createdAt,_that.updatedAt);case _:
  return null;

}
