Dart 聚合物铁弹性混合物'；s Don'；不工作，但上课
我让Polymer iron flex布局使用类在AngularDart组件中工作。由于它会生成一个弃用警告，我想我应该尝试推荐的替代方案：mixin的。它们不起作用 目前，我的Artister_component.dart中有此导入：Dart 聚合物铁弹性混合物'；s Don'；不工作，但上课,dart,polymer,angular-dart,Dart,Polymer,Angular Dart,我让Polymer iron flex布局使用类在AngularDart组件中工作。由于它会生成一个弃用警告，我想我应该尝试推荐的替代方案：mixin的。它们不起作用 目前，我的Artister_component.dart中有此导入： import 'package:polymer_elements/iron_flex_layout.dart'; 我还尝试将其添加到index.html中 <link rel="import" href="packages/polymer_ele

我已经尝试将导入放在index.html和我的主css文件中，并且不影响样式设置。考虑到这些课程很有效，你会认为mixim的也会有效。我不断挖掘，找到了答案。我还发现该方法已被弃用。My pubspec定义了以下版本：

polymer_elements: ^1.0.0-rc.8
