Solution: When AndroidManifest.xml changes aren’t seen in your Flutter dev/test app

As a brief note, if you’re developing an Android app with Flutter and then find that the changes you made to your AndroidManifest.xml file aren’t being seen in your app, you’ll probably need to uninstall your dev/test app and completely reinstall it with flutter run.

svn commit command - how to commit changes with svn

Here's a quick example of an svn commit command in what I think is a very typical scenario. Assuming that I just made a few changes to some files in a directory, to commit those changes back to the repository, I just issue an "svn commit" command like this, incuding a nice svn commit message:

svn commit --message "Enabling build processes to support multiple platforms"

(Don't forget -- a good SVN commit message can really help you out later. I find it helps to say both what I did, and why I did it.)
