- Before the upgrade, it was version 1.12.13, and now I want to upgrade to version 2 of flutter
- View branch
flutter channel
- It should be noted here that the package of which branch will be updated when which branch is updated
- run update
flutter upgrade
- report an error
- I checked a lot of online saying to switch to the dev (flutter channel dev) branch and then force the update, but if I want to download the stable version, I don't switch the branch, and force the update directly
- Force an update to run
flutter upgrade --force
- At this time, if the network is not good, it will be stuck and it will not continue. I have been running this command, and the rest of the configuration has not changed. It happened that the update was successful when the network was good.
- The following screen appears, the installation is successful
- Then run flutter doctor and flutter --version and the version number appears and you are done
