Is there a way to display a WebView in Flutter Web ?

推荐答案

您首先需要执行platformViewRegistry:

You need at first perform platformViewRegistry:

  ui.platformViewRegistry.registerViewFactory(
  'hello-world-html',
  (int viewId) => IFrameElement()
    ..width = '640'
    ..height = '360'
    ..src = 'https://www.youtube.com/embed/IyFZznAk69U'
    ..style.border = 'none');

查看该示例.在该示例中，导入了旧库(于19.09.19)，但是如果您在"flutter"上更改"flutter_web"，则该库必须正常工作.

Look at that example. In that example old library was imported (on 29.09.19), but if you change 'flutter_web' on 'flutter' it have to work.

此外，您不仅可以使用"IFrameElement"，还可以使用常规的html:

Also, you can use not only 'IFrameElement', it can be regular html:

    ui.platformViewRegistry.registerViewFactory("simple_div", (int viewId) {
  DivElement element = DivElement();
  ...
  return element;
