whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. AppKitModalWalletListing listing,
    2. bool installed,
    3. bool recent
    )?
)

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( AppKitModalWalletListing listing,  bool installed,  bool recent)?  $default,) {final _that = this;
switch (_that) {
case _ReownAppKitModalWalletInfo() when $default != null:
return $default(_that.listing,_that.installed,_that.recent);case _:
  return null;

}
}
