maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>({
  1. TResult delegated(
    1. StakeDelegatedAccountInfo info
    )?,
  2. TResult initialize(
    1. StakeInitializedAccountInfo info
    )?,
  3. TResult unknown(
    1. Map<String, dynamic> info
    )?,
  4. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>({TResult Function( StakeDelegatedAccountInfo info)?  delegated,TResult Function( StakeInitializedAccountInfo info)?  initialize,TResult Function( Map<String, dynamic> info)?  unknown,required TResult orElse(),}) {final _that = this;
switch (_that) {
case StakeProgramDelegatedAccountData() when delegated != null:
return delegated(_that.info);case StakeProgramInitializedAccountData() when initialize != null:
return initialize(_that.info);case StakeProgramUnknownAccountData() when unknown != null:
return unknown(_that.info);case _:
  return orElse();

}
