Flutter：firebase_auth 取决于 firebase_auth_platform_interface 错误

Question

I am trying to use firebase for my project. When I click on PUB GET, I get this error

"Because firebase_auth >=3.5.0 depends on firebase_auth_platform_interface ^6.4.0 which depends on collection ^1.16.0, firebase_auth >=3.5.0 requires collection ^1.16.0. And because every version of flutter_test from sdk depends on collection 1.15.0, firebase_auth >=3.5.0 is incompatible with flutter_test from sdk. So, because quick_chat depends on both flutter_test from sdk and firebase_auth ^3.5.1, version solving failed. pub get failed (1; So, because quick_chat depends on both flutter_test from sdk and firebase_auth ^3.5.1, version solving failed.)"

Pubspec.yml file:

 dependencies:
   flutter:
     sdk: flutter

  firebase_auth: ^3.5.1
  firebase_core: ^1.20.0
  cloud_firestore: ^3.4.1

How do I solve this?

Answer 1

The problem here is:

• flutter_test depends on collection 1.15.0
• firebase_auth depends on collection ^1.16.0

And package manager cannot decide which version to use.

What you can do here:

Option 1: Upgrade flutter_test (I believe it comes with SDK, so you need to upgrade Flutter SDK)

Option 2: Downgrade firebase_auth to the version that depends on collection 1.15.0

Option 3: Specify dependency_overrides (this will force chose the version of the library, use as last resort):

dependency_overrides:
  collection ^1.16.0
