Is there any way to use the firebase realtime db emulator with flutter web? I know is not yet available in FlutterFire but there might be some workaround.
As you've noticed the FlutterFire plugin for Firebase's Realtime Database does not currently support web clients.
I don't know of a workaround for that plugin, but typically use package:firebase/firebase.dart myself when accessing Realtime Database from Flutter Web. I'm not sure if that supports connecting to the emulator yet, but if not, it's probably worth filing a feature request on the repo or (even better) a PR for it.

I have a flutter app, works well on mobile, am trying to have the same app on web. am using moor to sync and store data locally incase there is no internet and when internet is back it syncs with the server. Now when I try to run the same app on the web, moor is complaining
Error: MissingPluginException(No implementation found for method getDatabasesPath on channel com.tekartik.sqflite)
the plugin says it supports web, from here. Am not finding much information on how to resolve this, how can I configure moor to run on the web without that error?
The plugin moor you are using is built on top of sqlite, which itself is not supported on web, and at bottom of moor plugin page also it's mentioned that web support is experimental now.
Sqlite plugin doesn't has support for web yet, but it does support android, ios and Macos. I would suggest anyone facing this problem to use other databases or cloud based databases instead of sqlite if you are using flutter web. Hope the plugin gets supported on web also.
Update:
You can try this example to use sqlite on web, it might work.
Got the same error when first run the web app.
If you follow clean architecture you can easily provide the right "database" instance.
This is what I did:
Create a local data store interface
Check if web using kIsWeb
If kIsWeb it true I return an in memory cache otherwise I just return the mobile app database that you already implemented for you Android and iOS apps
We just launched a project that uses Flutter and Firebase services: Auth, Firestore, Functions.
We just find out that Firebase doesn't work on Huawei phones.
Which backend service is the fastest and most reliable to use in Flutter to migrate the entire project?
I just migrated an entire project to Supabase and it is a great alternative, Also as mentioned in the comments by Ranvir, AWS Amplify is another alternative, but needs more work.
I'm wondering how stable the current version is for Flutter Web?
It looks like the authentications works well. But what about the Real-Time database & Firestore? Are you able to use these in the latest release? I would like to know if the current version works well with:
SVG's
Responsive enough?
Firestore possible?
Real-Time database supported? And do they use the same packages as the mobile version?
Multiple browsers compatible
Functions, are there CORS policy issues?
Uploading files
You can definitely use firestore, just like you would with apps. But as far as overall stability of web, I would say its not fully stable or else it wouldn't be in the "stable" channel instead of "beta".
It is capable of doing most of the things that you can do on a mobile device within the app. The things that aren't fully stable yet are the web specific things. It is already responsive, and firestore and real time database work fine. It should be compatible on all browsers (but i haven't test that). I'm not sure what you mean by uploading files, but if you mean to some database then that should be no problem either.
I think for now, if you're just trying to set up a simple website it should be good enough for that, but if you want to do something more complex, I would wait until it is in the "stable" channel.
I have an existing flutter mobile application, which I want to convert into flutter web application. I used SQFlite as a local storage DB in mobile app, how can I use that for web application?
As far as i know, the web does not support sqlite in any acceptable ways (yes there are in memory solution but no
persistency, see https://github.com/tekartik/sqflite/issues/212).
Since there is no decent solution on the web, as of today, support is not planned.
IndexedDB or any solution on top of it should be considered for storage on the Web.
I am using firebase plugin to authentication with email and password in flutter web. I am done with this one.
Now I want to authenticate flutter web with phone_auth. I am using the same plugin and in this plugin, a future method which is called signInWithPhoneNumber(String phoneNumer, ApplicationVarifier verifier). I follow the rule on the firebase for application verifier. There, I learn about ReCaptchaVarifier which verifies the user with reCaptcha technique. But there is no way to integrate reCaptcha in flutter web.
If you solved my problem then it will be great opportunity for me to getting my job. Thanks I am waiting for your response
Flutter for Web is currently in development, therefore firebase support isn't yet ready... It may come in the near future. Good luck with your project!
As at now Flutter Web is not yet ready for Production and it does not support these yet.
You should consider using other dart frameworks.
And No, you can not write HTML code for flutter web.
