How to upgrade Flutter SDK and package dependencies

To upgrade Flutter SDK, run the following command:

flutter upgrade

If the preceding command didn’t work for you, just add the –force flag, like this:Advertisements

flutter upgrade --force

To update all the dependencies listed in a Flutter project’s pubspec.yaml file to the latest compatible versions, execute this command:

flutter pub upgrade

To check outdated plugins, run:

flutter pub outdated

Then you’ll see something similar to this:
