flutter firebase version solving failed

Question

Because firebase_storage >=2.0.0 depends on firebase_core ^0.3.0 and firebase_auth 0.6.6 depends on firebase_core ^0.2.5+1, firebase_storage >=2.0.0 is incompatible with firebase_auth 0.6.6. And because no versions of firebase_auth match >0.6.6 <0.7.0, firebase_storage >=2.0.0 is incompatible with firebase_auth ^0.6.6. So, because store_manager_erp_next depends on both firebase_auth ^0.6.6 and firebase_storage ^2.1.0+1, version solving failed.

I am new in flutter, please help me to solve this issue

Answer 1

Change

 firebase_auth:  ^0.6.6

to

 firebase_auth:  ^0.8.0

You might also need to check other dependencies if the constraints are outdated.

You can also use the workaround mentioned in https://github.com/flutter/flutter/issues/12627#issuecomment-400037580

export FLUTTER_ROOT="/Users/something/flutter"
pub upgrade

to get information for what dependencies updates are available.

Answer 2

You need to migrate your project to AndroidX . Please see the following documentation for detailed steps on it...

Migrate to Android X

Or else, just downgrade the firebase_auth version to the old version that works fine without androidX migration

Answer 3

just add this line of code in your pubspec

dependency_overrides:
  firebase_core: 0.3.0

this will override the dependency, and you can use whatever version you want. you might need to change it the version of the package.

my code example:

dependencies:
  flutter:
    sdk: flutter

  cupertino_icons: ^1.0.0
  file_picker: ^3.0.0
  hive: ^2.0.0
  hive_flutter: ^1.0.0

dependency_overrides:
  path_provider: 2.0.1

Answer 4

consult this link https://github.com/FirebaseExtended/flutterfire/issues/4650 and replace the version of your project with the corresponding version

Answer 5

Try run pub get by omitting the version name of the package which is causing you the issue like this

firebase_storage:

This will get you out the issue.

Answer 6

you can downgrade your google sign in version to stable one like

google_sign_in: ^4.5.9

to know the most stable one go to

https://pub.dev/packages/google_sign_in/versions

and choose latest one before beta version pubspec.yaml file

environment: sdk: ">=2.12.0 <3.0.0"

dependencies: flutter: sdk: flutter

cupertino_icons: ^1.0.2 get: ^4.2.4 google_sign_in: ^4.5.9 firebase_core: "0.7.0" firebase_auth: "^0.20.1"
