request: generate or support web/firebase-messaging-sw.js

[jakusb]

Is there an existing feature request for this?

• I have searched the existing issues.

Command

flutterfire configure --include-messaging

Description

Running "flutterfire configure" works like a charm for normal Firebase operations, but is missing out on Cloud Messaging assistance. We now need to still manually and hardcoded introduce our own firebase-messaging-sw.js for web.

Steps to reproduce the behavior:
Run "flutterfire configure"
Notice web/firebase-messaging-sw.js is not created

Expected behavior
web/firebase-messaging-sw.js or any working equivalent should be created, optionally through flag or always

Reasoning

messaging is important component of many apps.
Hardcoding should be avoided where possible

Additional context and comments

This is a major headache and one which is hard to find the cause or a solution until you stumble on firebase/flutterfire#11678
This should be documented somehow, maybe as interim workaround flutterfire configure prints a warning when configuring web, if firebase_messaging was added in pubspec.

For flavors when you generate that file:
my solution by using IndexedDB and Hive
firebase/flutterfire#12146
While the best solution is
flutter/flutter#141371

I think this is the official reference to how to create the service worker:
