Question

我正在尝试用颤动的代码显示HTML

通过使用flutter_html：^ 0.10.4

import'package：flutter_html / flutter_html.dart';

但是在显示html时滚动显示黄色错误

代码

  body: Builder(
    builder: (BuildContext context) {
      return Container(
          child: Column(
        children: <Widget>[
          _buildHeader(context),
          loading
              ? Container(

我正在尝试使其完全包含HTML内容，并将其设置为具有行高的rtl样式。

HTML将显示图像，文本和YouTube视频。

Answer 1

使用ListView代替Column 像这样：

ListView(
  childern: <Widget>[
    //your widgets
  ],
);

或使用SingleChildScrollView包裹您的列，如下所示：

SingleChildScrollView(
  child: Column(
    childern: <Widget>[
      //your widgets
    ],
  ),
);

带有垂直文本修饰符的HTML插件
