How to insert prefabricated rich text?

[greenking19]

I have some rich text that needs to be requested back from the backend, then inserted into the HtmlEditor for editing and then saving。
Need to use that method to call it? I can't find it

I found two functions, setText and instertHeml.
If I want to call the call immediately in initState, it will report an error.
This seems to be a webview problem🥲
👇🏻 Now I solved the error like this. But it always feels wrong……

@override
void initState() {
  super.initState();
  init();
}

void init() async {
  String data = await getData();
  await Future.delayed(Duration(seconds: 1));
  controller.setFocus();
  controller.insertHtml(data);
}
