Let's see how to update/upgrade flutter to a new version.
The upgrade will run for few mins, and it depends on your internet speed.
At last, verify the flutter doctor output and fix any obvious issues.
Step 1: Run Flutter doctor in the command prompt.

If there is a new version available, then you will see a message like shown above.
Step 2: Run Flutter upgrade command as suggested in the command prompt.

Thanks,
