maybeMap<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeMap<TResult extends Object?>({
  1. TResult legacy(
    1. CompiledMessageLegacy value
    )?,
  2. TResult v0(
    1. CompiledMessageV0 value
    )?,
  3. required TResult orElse(),
})

A variant of map that fallback to returning orElse.

It is equivalent to doing:

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

Implementation

@optionalTypeArgs TResult maybeMap<TResult extends Object?>({TResult Function( CompiledMessageLegacy value)?  legacy,TResult Function( CompiledMessageV0 value)?  v0,required TResult orElse(),}){
final _that = this;
switch (_that) {
case CompiledMessageLegacy() when legacy != null:
return legacy(_that);case CompiledMessageV0() when v0 != null:
return v0(_that);case _:
  return orElse();

}
