whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>({
  1. TResult? raw(
    1. String name,
    2. Uint8List bytes
    )?,
})

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 name,  Uint8List bytes)?  raw,}) {final _that = this;
switch (_that) {
case _JsModuleBytecode() when raw != null:
return raw(_that.name,_that.bytes);case _:
  return null;

}
}
