copyWith method
FdcDataSetFilterContext
copyWith({
- FdcFormatSettings? formatSettings,
- Object? selected = _fdcUnsetFilterContextValue,
Returns a copy with changed filter context values.
selected intentionally uses a sentinel parameter so copyWith() keeps
the current selection predicate, while copyWith(selected: null) clears
it. Passing a non-null value must still be a bool.
Implementation
FdcDataSetFilterContext copyWith({
FdcFormatSettings? formatSettings,
Object? selected = _fdcUnsetFilterContextValue,
}) {
if (!identical(selected, _fdcUnsetFilterContextValue) &&
selected != null &&
selected is! bool) {
throw ArgumentError.value(
selected,
'selected',
'Expected bool, null, or omitted value.',
);
}
return FdcDataSetFilterContext(
formatSettings: formatSettings ?? this.formatSettings,
selected: identical(selected, _fdcUnsetFilterContextValue)
? this.selected
: selected as bool?,
);
}
