Flutter Pubnub version solving failed - flutter

Question

got this exception when I add pubnub: ^1.4.4 into pubspec.yaml
Because pubnub >=1.0.2 <3.2.0 depends on dio ^3.0.0 and talad_flutter
depends on dio ^4.0.0, pubnub >=1.0.2 <3.2.0 is forbidden. So, because
talad_flutter depends on pubnub ^1.4.4, version solving failed.
I've tried to reduce version of each library but still not luck.
here is my full pubspec.yaml

Answer 1

According to PubNub Engineering
This is a very outdated version of the pubnub package. Currently we are on 3.x and about to release 4.x
In general, you can always solve this kind of issue with Dart using dependency overrides
