flutter depends on firebase_analytics 0.0.4 which requires SDK version >=1.8.0 <2.0.0, version solving failed

Question

Because flutter_chat_app depends on firebase_analytics 0.0.4 which requires SDK version >=1.8.0 <2.0.0, version solving failed. pub get failed (1) exit code 1

 dependencies:
  flutter:
    sdk: flutter
  image_picker: 0.1.1
  google_sign_in: 0.3.1
  firebase_analytics: 0.0.4
  firebase_auth: 0.2.0
  firebase_database: 0.0.12
  firebase_storage: 0.0.5

Answer 1

Your dependency have version constraints that request quite outdated versions of dependencies.

Check each dependency in https://pub.dartlang.org and change the version constraint to versions that allow the version you want

image_picker: ^0.5.0

which allows all version 0.5.x

or

google_sign_in: ^4.0.0

which allows all versions 4.xx

Please note the different effect of ^ for versions that start with 0. vs versions that start with 1. (or any other number other than 0 .

Please also check the CHANGELOG.md tab. Most "official" plugins require you to migrate your project to AndroidX.

Answer 2

Just come down to the issue, you have to add dev dependency. you can add something called dependency override into the pubspec file.

like that :

dependency_overrides:
image_picker: ^0.5.0
