Bug Fix/ Minor Adjustment/ Porting to Flutter (small IOS app)

I have a test app (code in zip?) on iOS – I think it was done in non flutter way. It will be nice to port to flutter.

I want someone’s help to make a minor adjustment in text messages in side. This is low priority task and mainly I want to make connection with some senior flutter developer for long term. How to test without pushing to store is main thing.
