toJson method
Abstract function that concrete classes must implement. This must encode the internal data model to a JSON compatible representation.
While not required, it is suggested to call removeNull before returning.
Implementation
@override
Map<String, dynamic> toJson() {
return JsonClass.removeNull({
'childBuilder': childBuilder,
'debugLabel': debugLabel,
'initialScrollOffset': initialScrollOffset,
'keepScrollOffset': keepScrollOffset,
'varName': 'scrollController' == varName ? null : varName,
'child': child?.toJson(),
...args,
});
}
