dependency issues why I try to run/debug my app

Question

I'm new to making an app with flutter/dart and I'm running into some issues with the dependecies in the pubspec.yaml. I'm trying to make an app from a template to learn about how to work with repositories from github. After I brought in the code and repaired all the errors I tried to run/debug it and keep getting this from the output terminal:

Because google_sign_in >=5.4.0 depends on google_sign_in_platform_interface ^2.2.0 which depends on quiver ^3.0.0, google_sign_in >=5.4.0 requires quiver ^3.0.0. And because cloud_firestore >=0.14.0-dev.1 <0.17.0-1.0.nullsafety.0 depends on quiver ^2.0.0, google_sign_in >=5.4.0 is incompatible with cloud_firestore >=0.14.0-dev.1 <0.17.0-1.0.nullsafety.0. Because cloud_firestore >=0.13.3 <0.14.0-dev.1 depends on firebase_core ^0.4.4 and cloud_firestore >=0.11.0 <0.13.3 depends on firebase_core ^0.4.0, cloud_firestore >=0.11.0 <0.14.0-dev.1 requires firebase_core ^0.4.0. Thus, if google_sign_in >=5.4.0 and cloud_firestore >=0.11.0 <0.17.0-1.0.nullsafety.0 then firebase_core ^0.4.0. And because txapita depends on cloud_firestore >=0.11.0 <0.14.0+1, google_sign_in >=5.4.0 requires firebase_core ^0.4.0. So, because txapita depends on both firebase_core ^2.4.1 and google_sign_in ^5.4.2, version solving failed. pub get failed (1; So, because txapita depends on both firebase_core ^2.4.1 and google_sign_in ^5.4.2, version solving failed.) exit code 1

Also, how do I get rid of txapita from the whole project if I can. It seems a lot of the code in the repository needs that package but I can't find the source package.

I've tried changing the versions to the versions in the error message Here is my pubspec with things I've tried:

If I change the name to the name of the app it adds more errors to the output terminal when I save, is that how I get rid of the packages from the code?

Answer 1

Rather than using null or any find the package version by searching the package.

Link to PUB: https://pub.dev/

E.g. : cloud_firestore: ^4.3.1

Try running flutter pub upgrade --major-versions
