What causes this issue?
The error is mainly triggered when you upgrade your Flutter SDK version but the platform plugin remains on the older version. Alternatively, the error can also occur if the platform plugin version of Flutter isn’t compatible with the SDK version you’re using.
How to fix this?
Here are four fixes you can try out.
Update your download cache
The first thing you should do is upgrade your download cache for your Flutter SDK. You can do this by running a simple command given below.
flutter pub upgrade
Update Flutter
In case you’re using an experimental version, you need to update Flutter to a stable variant for your project to work properly. You can do this by running these commands one at a time:
flutter channel stable
flutter upgradeOnce you’re done, update the pub and you’re good to go.
flutter pub upgradeOverride dependencies
If upgrading the pub isn’t helping, you can manually override dependencies to fix any version mismatch issues. To do so, head over to your pubspect.yaml file and manually change the version number of your dependencies to the latest stable version available.
Clear the cache
