whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. @JsonKey.new(name: 'certificateFile') String? certFile,
    2. @JsonKey.new(name: 'certificate') List<String>? certStr,
    3. String? keyFile,
    4. @JsonKey.new(name: 'key') List<String>? keyStr,
    5. TLSCertificateUsage? usage,
    6. int? ocspStapling,
    7. bool? oneTimeLoading,
    8. bool? buildChain,
    )?
)

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: 'certificateFile')  String? certFile, @JsonKey(name: 'certificate')  List<String>? certStr,  String? keyFile, @JsonKey(name: 'key')  List<String>? keyStr,  TLSCertificateUsage? usage,  int? ocspStapling,  bool? oneTimeLoading,  bool? buildChain)?  $default,) {final _that = this;
switch (_that) {
case _TLSCertConfig() when $default != null:
return $default(_that.certFile,_that.certStr,_that.keyFile,_that.keyStr,_that.usage,_that.ocspStapling,_that.oneTimeLoading,_that.buildChain);case _:
  return null;
