Getting package version conflicts while installing Flutter packages

Question

I am trying to install a package jitsi_meet: ^4.0.0 in pubspec.yaml, while I am installing, I am getting this error with the termination of installation:

Running "flutter pub get" in edaffix-mobile-flutter-master...     
Because jitsi_meet >=4.0.0 depends on jitsi_meet_platform_interface ^2.0.0 which depends on plugin_platform_interface ^2.0.0, jitsi_meet >=4.0.0 requires plugin_platform_interface ^2.0.0.
And because firebase_storage_platform_interface 1.0.4 depends on plugin_platform_interface ^1.0.0 and no versions of firebase_storage_platform_interface match >1.0.4 <2.0.0, jitsi_meet >=4.0.0 is incompatible with firebase_storage_platform_interface ^1.0.4.
And because firebase_storage 7.0.0 depends on firebase_storage_platform_interface ^1.0.4 and no versions of firebase_storage match >7.0.0 <8.0.0, jitsi_meet >=4.0.0 is incompatible with firebase_storage ^7.0.0.
So, because edaffix depends on both firebase_storage ^7.0.0 and jitsi_meet ^4.0.0, version solving failed.



pub get failed (1; So, because edaffix depends on both firebase_storage ^7.0.0 and jitsi_meet ^4.0.0, version solving failed.)

I tried to install plugin_platform_interface: '^1.0.0 as an extra dependency but is not working. How can I solve this?

Answer 1

You can downgrade the jitsi_meet package to version ^2.1.0 and the error should disappear.

I got the version number by:

1. Leaving the jitsi_meet version as empty like this:

jitsi_meet:

This makes pub get the best compatible version of the package.

2. Searching the pubspec.lock file for jitsi_meet. There I saw this code block:

jitsi_meet:
  dependency: "direct main"
  description:
    name: jitsi_meet
    url: "https://pub.dartlang.org"
  source: hosted
  version: "2.1.0"

This means pub resolved the version number to 2.1.0

3. Specifying the version number in the pubspec.yaml file like this:

jitsi_meet: ^2.1.0
