在 Flutter 网页和移动应用中使用 Firebase

Question

I'm working on a Flutter app, compiled in both web AND mobile version. Everything worked like a charm until I decided to use Firebase.

I found that there are many libs that allow to use Firebase in Flutter, for mobile apps. I also found a lib that allows to use Firebase in Flutter web app.

The problem is: Firebase plugin for web version is using "dart:html" , which isn't supported for mobile versions of Flutter apps. On the other side, mobile libs aren't supported by web versions and I always get a PlatformException when using them in web app.

So here is my question: Does anyone know a Flutter's Firebase lib, that works on BOTH mobile AND web versions, so that I only have to compile in the platform I want, without having to change the code before?

EDIT: I know there is a way to write specific code for Android or iOS version, but I can't find any clue for writing specific code for the web version. This should be another way to solve the problem...

Any idea?

Answer 1

At the moment there is no single Flutter+Firebase library that works for both web and mobile apps, so you will need to use two (incompatible) libraries.

Work is being done to rectify that situation, but there's no timeline for its release.

Answer 2

What firebase plugins are you using?? As there are only limited firebase plugins avalaible to use on web which includes firebase_analytics firebase_auth cloud_firestore cloud_functions firebase_messaging firebase_storage firebase_core

if you are using any firebase plugin other than these then they are not supported for web
