Installation of flutter App by code and minor renaming work.

I'm looking for a Freelancer to help with installing an existing Flutter App, as well as slightly renaming features within the App. The App is cross-platform, so it will be applicable to both Android and iOS users. Testing of the App is also necessary, as there are 4-7 features that need to be tested once the App is installed. I'm open to new ideas from the Freelancer to ensure the App functions well after every step of the process.
