Fresh Flutter App Error: app:checkDebugAarMetadata-CodePudding

So, I'm using the command line and VScode. I'm just trying to get Flutter to run so I can try it out again, but I keep running into this error. I used it before a few months ago and now I'm trying to start a new app. Any ideas?

CodePudding user response：

You should set minSdkVersion on build.grade by lower number, like this

minSdkVersion 21

Hmm, I just reinstalled Java and it started working. Specifically, I made sure Java 8 was working.
