英文:
"flutter build web" builds an empty index.html file
问题
当我尝试运行flutter create web将我的Flutter项目转换为Web应用程序时，我在Web浏览器中打开index.html文件，但页面是空白的。您有任何想法为什么会这样吗？以下是index.html文件的内容：
<!DOCTYPE html>
<html>
<head>
<!--

var serviceWorkerVersion = "4031280537";
</script>
<!-- This script adds the flutter initialization JS code -->
<script src="/flutter.js" defer></script>
</head>
<body>
<script>
window.addEventListener('load', function(ev) {
// Download main.dart.js
_flutter.loader.loadEntrypoint({
serviceWorker: {
serviceWorkerVersion: serviceWorkerVersion,
},
onEntrypointLoaded: function(engineInitializer) {
engineInitializer.initializeEngine().then(function(appRunner) {
appRunner.runApp();
});
}
});
});
</script>
</body>
</html>
在之前的帖子中，href曾经是问题，但在多次更改后，我开始认为这个解决方案在这里不起作用。flutter doctor也没有报告任何问题。我尝试过的其他href路径包括："/"、"/build/"、"/web/"和"/build/web/"。

In previous posts, the href has been the problem, but after changing it multiple times I've grown to think that that solution won't work here. flutter doctor does not report any problems either. Other href paths I have tried include: "/", "/build/", "/web/", and "/build/web/".

为了解决这个问题，我不得不使用Firebase托管网站并关闭树摇。这两件事情都能够解决我的问题。

In order to fix this problem, I had to host the website with Firebase and turn tree shaking off. Doing both of these things was able to fix the problem for me.
