You can use buildView and finishView methods in your type to pass new view vars to the form template. You can pass stuff from form options or form data class for example.

您可以在类型中使用buildView和finishView方法将新视图变量传递给表单模板。例如，您可以从表单选项或表单数据类传递内容。

Method buildView is run before children views are built so you cannot access child views there (then you should use finishView which are run after children views are built).

方法buildView在构建子视图之前运行，因此您无法在那里访问子视图（那么您应该使用在构建子视图之后运行的finishView）。
