buildWithChild method

@override Iterable<Component> buildWithChild(BuildContext context, Component? child)

A build method that receives an extra child parameter.

This method may be called with a child different from the parameter passed to the constructor of SingleChildStatelessComponent. It may also be called again with a different child, without this component being recreated.

Implementation

@override
Iterable<Component> buildWithChild(
    BuildContext context, Component? child) sync* {
  final builder = this.builder;
  assert(
    builder != null || child != null,
    '$runtimeType used outside of MultiProvider must specify a child',
  );
  yield _InheritedProviderScope<T?>(
    owner: this,
    // ignore: no_runtimetype_tostring
    debugType: kDebugMode ? '$runtimeType' : '',
    child: builder != null
        ? Builder(
            builder: (context) => builder(context, child),
          )
        : child!,
  );
}
