getViewFactory function

Expression getViewFactory(CompileDirectiveMetadata component, String name)

Returns a callable expression for the component view factory named name.

If component is generic, the view factory will flow the type parameters of the parent view as type arguments to the embedded view.

Note: It's assumed that name originates from an invocation of getViewFactoryName with the same component.

Implementation

o.Expression getViewFactory(
  CompileDirectiveMetadata component,
  String name,
) {
  final viewFactoryVar = o.variable(name);
  if (component.originType!.typeParameters.isEmpty) {
    return viewFactoryVar;
  }
  final parameters = [o.FnParam('parentView'), o.FnParam('parentIndex')];
  final arguments = parameters.map((p) => o.variable(p.name)).toList();
  return o.FunctionExpr(parameters, [
    o.ReturnStatement(o.InvokeFunctionExpr(
      viewFactoryVar,
      arguments,
      component.originType!.typeParameters.map((t) => t.toType()).toList(),
    )),
  ]);
}
