Flutterfire: [Messaging] flutter_driver and firebase_messaging are incompatible

[deimantasa]

Description
Firebase Messaging (7.0.0) and latest Flutter Master (1.22.0-2.0.pre.36) doesn't work.

Error

Because every version of flutter_driver from sdk depends on platform 3.0.0-nullsafety.1 and firebase_messaging 7.0.0 depends on platform ^2.0.0, flutter_driver from sdk is incompatible with firebase_messaging 7.0.0.
And because no versions of firebase_messaging match >7.0.0 <8.0.0, flutter_driver from sdk is incompatible with firebase_messaging ^7.0.0.
So, because fluid depends on both firebase_messaging ^7.0.0 and flutter_driver any from sdk, version solving failed.

To Reproduce

1. Create new project;
2. Copy-Paste to pubspec.yaml (only added flutter_driver and firebase_messaging)
3. Write flutter pub get
4. Error will appear.

Expected behavior
Libs should be retrieved without an error.

Additional context
Works fine in Flutter 1.21.0-10.0.pre.139,.

Issue replicable on latest Master (1.22.0-2.0.pre.36). Doesn't occur on latest stable though (1.20.2)

Because every version of flutter_driver from sdk depends on platform 3.0.0-nullsafety.1 and firebase_messaging 7.0.0 depends on platform ^2.0.0, flutter_driver from sdk is incompatible with firebase_messaging 7.0.0.

And because no versions of firebase_messaging match >7.0.0 <8.0.0, flutter_driver from sdk is incompatible with firebase_messaging ^7.0.0.

So, because test_bug depends on both firebase_messaging ^7.0.0 and flutter_driver any from sdk, version solving failed.
pub get failed (1; So, because test_bug depends on both firebase_messaging ^7.0.0 and flutter_driver any from sdk, version solving failed.)

I also tried with other firebase plugins (eg: firebase_core, firebase_auth) which compiles properly along with flutter driver, but issue seems to be happening only with firebase_messaging.

The same setup works on previous master version (1.21.0-10.0.pre.139).

[Salakar]

We should move e2e tests & driver dev dependency to the example app in messaging. No reason they need to stay as dev deps on the plugin itself - would someone be willing to send up a PR to do that?

[yvrez]

hello any update on this one ? i had to move to Beta Branch to make my project compile again with messaging 7.0.0. Thanks !

[preetjdp]

Hey @yvrez I've made the PR that fixes the issue, it is still to be reviewed (https://github.com/FirebaseExtended/flutterfire/pull/3343)

In the meantime, you can just use the package directly

firebase_messaging:
    git:
      url: git://github.com/preetjdp/flutterfire.git
      ref: fix-3312
      path: packages/firebase_messaging

[yvrez]

thanks @preetjdp thanks i'm going to do that !

[shaynekellyii]

Any update on this? Flutter 1.22 was just pushed to the Flutter beta channel this morning.

[kauaicreative]

Hey @yvrez I've made the PR that fixes the issue, it is still to be reviewed (#3343)

In the meantime, you can just use the package directly

firebase_messaging:
    git:
      url: git://github.com/preetjdp/flutterfire.git
      ref: fix-3312
      path: packages/firebase_messaging

hmm, not working from here:

pub upgrade failed (server unavailable) -- attempting retry 6 in 32 seconds...
Package doesn't exist (the pubspec for firebase_messaging 7.0.1 from git has version 7.0.0).

[shaynekellyii]

@kauaicreative I would just fork flutterfire yourself for now and remove the platform dependency from the pubspec.yaml of firebase_messaging and import that in your project until it's done

[acoutts]

@Ehesp do you know if we'll have a quick fix for this on your new branch anytime soon?

[acoutts]

A quick fix that seems to satisfy the install command now:

dependency_overrides:
  # For firebase_messaging
  platform: 3.0.0-nullsafety.1

It's a tough time for a lot of packages right now because we're halfway between migrating everything for NNBD coming soon. It's gonna be a rocky migration for flutter devs.

[acoutts]

cc @Salakar in the current release of flutter, only the stable branch is able to use this package the moment.

[Ehesp]

Currently in the process of reworking messaging - have removed the platform dependency altogether. I'll get someone to look into sorting this in a patch.

[MrAlek]

@Ehesp Any updates on this? :)

[dackers86]

@MrAlek Messaging rework was announced yesterday https://twitter.com/mikediarmid/status/1319298281290203139. I believe this should solve this issue?

[MrAlek]

@dackers86 Just saw this, thanks for the link!

Looks amazing, great work @Ehesp @Salakar & team 👏 Can't wait to try out!
