获取应用程序/ dart脚本unsuopported [英] Fetching application/dart script unsuopported
问题描述
我有这样的dart应用程序的index.html文件设置：
<！DOCTYPE html>
< html>
< head>
< title> basic_app< / title>
< script defer src =main.darttype =application / dart>< / script>
< script defer src =packages / browser / dart.js>< / script>
< / head>
< body>
< / body>
< / html>
Chrome已开始向我发出警告：
获取无效类型/语言属性的脚本已被弃用，并会在2017年1月左右在M56中删除。请参阅 https://www.chromestatus.com/features/5760718284521472 了解更多详情。
我必须改变什么才能摆脱这个警告？
我相信这是由这行引起的：
< script defer src =main.darttype = application / dart>< / script>
Chrome不知道Dart，加载Dart脚本标记。 pub build 不会删除Dart脚本标记。有 dart_to_js_script_rewriter 转换器删除了Dart脚本标记，因此只有dart2js-transpiled JS代码
$ b 添加包为
dev _ $ b dev_dependencies：
dart_to_js_script_rewriter：^ 1.0.1
和变压器配置结束：
- dart_to_js_script_rewriter
I have my index.html file setup for a dart application like this:
<!DOCTYPE html>
<html>
<head>
<title>basic_app</title>
<script defer src="main.dart" type="application/dart"></script>
<script defer src="packages/browser/dart.js"></script>
</head>
<body>
</body>
</html>
Chrome has started throwing a warning at me that says:
Fetching scripts with an invalid type/language attributes is deprecated and will be removed in M56, around January 2017. See https://www.chromestatus.com/features/5760718284521472 for more details.
What do I have to change to get rid of this warning? I believe it is caused by this line:
<script defer src="main.dart" type="application/dart"></script>
Chrome doesn't know about Dart, only Dartium can load Dart script tags. pub build doesn't remove the Dart script tag. There is the dart_to_js_script_rewriter transformer that removes that Dart script tag so that only the dart2js-transpiled JS code is loaded in production:
Add the package as dev_dependency`
dev_dependencies:
dart_to_js_script_rewriter: ^1.0.1
and the transformer configuration at the end of the transformers configuratino:
transformers:
- dart_to_js_script_rewriter
