The current Dart SDK version is 3.2.3

The current Dart SDK version is 3.2.3.

Because cloud_firestore >=5.4.2 <5.4.3 depends on cloud_firestore_web ^4.3.1 and cloud_firestore >=5.4.3 depends on cloud_firestore_web ^4.3.2, cloud_firestore >=5.4.2 requires cloud_firestore_web ^4.3.1. So, because cloud_firestore_web >=4.3.0 requires SDK version >=3.4.0 <4.0.0 and chatter depends on cloud_firestore ^5.4.2, version solving failed.
