Flutter无法为脚本注册作用域的ServiceWorker，该脚本的MIME类型不受支持 [英] Flutter Failed to register a ServiceWorker for scope with script, The script has an unsupported MIME type
问题描述
我有一个具有FlutterFire功能的功能齐全的Flutter应用程序，其中的android捆绑包运行得很好，但是Web客户端启动时却出现了一个奇怪的错误.我也不能用flutterfire调用任何firebase函数.(简单的Firebase查询就可以了)
I have a fully functioning Flutter app with FlutterFire, where the android bundle works just fine, but the web client gives a strange error upon start. I cannot call any firebase function with flutterfire with it either. (simple firebase queries works just fine)
启动时或尝试调用 FirebaseFunctions.instance.httpsCallabe('... :

我没有firebase-messaging-sw.js 文件.我只按照文档的建议做了 https://firebase.flutter.dev/docs/messaging/overview/#5-web-only-add-the-sdk .
I don't have a firebase-messaging-sw.js file. I only did what the documentation recommended https://firebase.flutter.dev/docs/messaging/overview/#5-web-only-add-the-sdk.

我必须创建文件并提供默认设置，这样应用程序才能正常运行而不会引发错误.
I had to create the file and provide the default settings so the app can work without throwing errors.
