I need a flutter app developer -- 2

I am looking for an experienced flutter app developer to create an Android app for me. I do not require a modern UI design, but instead need an experienced and reliable developer to do some minor updates to the existing app. The updates include changing the logo and app icon, set up push notification, change colour,otp ,upload booking details, and uploading it to the Google Play Store. Furthermore, I need the app to have basic data storage and analytics, as well as user authentication integrated into it. If you think you have what it takes to create a professional and reliable application that meets my criteria, then I’d love to hear from you.
