whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String id,
    2. String name,
    3. String email,

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 name,  String email,  bool emailVerified,  String? image,  DateTime? createdAt,  DateTime? updatedAt,  bool twoFactorEnabled,  String? username,  String? displayUsername,  bool isAnonymous,  String? phoneNumber,  bool phoneNumberVerified,  String? role,  bool banned,  String? banReason,  DateTime? banExpires)?  $default,) {final _that = this;
switch (_that) {
case _User() when $default != null:
return $default(_that.id,_that.name,_that.email,_that.emailVerified,_that.image,_that.createdAt,_that.updatedAt,_that.twoFactorEnabled,_that.username,_that.displayUsername,_that.isAnonymous,_that.phoneNumber,_that.phoneNumberVerified,_that.role,_that.banned,_that.banReason,_that.banExpires);case _:
  return null;
