Inside your project root, run below command flutter upgrade So how do I upgrade my app to use the latest Flutter version? Or is it always built using the latest version of the SDK? Can't I target my app to build with specific version of Flutter? I have tried running "flutter upgrade" within my app, but that was to upgrade the SDK, not the Flutter version of the app. In the future, how would I know which version was this app running?


I have an existing Flutter app that I built half a year ago.
