buildSingleWidget method

DataScopeWidget buildSingleWidget(ScopeManager parentScope, ItemTemplate itemTemplate, { required int itemIndex, required dynamic itemData, Key? key, })

Implementation

DataScopeWidget buildSingleWidget(
    ScopeManager parentScope, ItemTemplate itemTemplate,
    {required int itemIndex, required dynamic itemData, Key? key}) {
  // create a new scope for each item template
  ScopeManager templatedScope = parentScope.createChildScope();

  // add the item's index and data to the templated scope
  templatedScope.dataContext.addDataContextById(itemTemplate.name, itemData);
  templatedScope.dataContext.addDataContextById(itemTemplate.indexId, itemIndex);

  WidgetModel model =
      templatedScope.buildWidgetModelFromDefinition(itemTemplate.template);
  Widget templatedWidget = templatedScope.buildWidgetFromModel(model);
  // Widget templatedWidget =
  //     templatedScope.buildWidgetFromDefinition(itemTemplate.template);

  // wraps the templated widget inside a DataScopeWidget so we can constrain the data scope
  return DataScopeWidget(
    scopeManager: templatedScope,
    child: templatedWidget,
    key: key,
  );
