maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. Glyph glyph,
    2. VoidCallback? onPressed,
    3. String? tooltip,
    4. bool isLoading,
    5. bool? isSelected,
    )?, {
  2. 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( Glyph glyph,  VoidCallback? onPressed,  String? tooltip,  bool isLoading,  bool? isSelected)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _IconButtonData() when $default != null:
return $default(_that.glyph,_that.onPressed,_that.tooltip,_that.isLoading,_that.isSelected);case _:
  return orElse();

}
}
