maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String? icon,
    2. double? iconSize,
    3. String? iconColor,
    4. String? backgroundColor,
    5. double? buttonSize,
    6. double? borderRadius,
    7. bool? useAvatarAsIcon,
    )?, {
  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( String? icon,  double? iconSize,  String? iconColor,  String? backgroundColor,  double? buttonSize,  double? borderRadius,  bool? useAvatarAsIcon)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _FabConfiguration() when $default != null:
return $default(_that.icon,_that.iconSize,_that.iconColor,_that.backgroundColor,_that.buttonSize,_that.borderRadius,_that.useAvatarAsIcon);case _:
  return orElse();

}
