As a seasoned freelancer with extensive experience in Flutter and Dart programming, I am more than qualified to address any issues you're facing with your app. I understand the frustration that can come with app crashes, missing functionality, and poor performance - but rest assured, my team and I are experts in troubleshooting and resolving these intricate problems. With a proficiency in both Android and iOS development, we can ensure the app is stable and functional on all platforms.
With great attention to detail, we'll look into the chat screen crash issue and validate the withdrawal form meticulously-and add any required error handling. Moreover, incorporating back buttons, adding loading icon in home screen, commenting a feature (for iOS), integrating Admob ad codes are bread-and-butter tasks for us that we execute seamlessly.
Lastly, my dedicated team possesses hardware requirements such as a Mac to upload to Appstore while also having expertise in store deployment that ensures your updated icon and screenshots will be aptly deployed. Let's partner together to not only repair your app's performance but even enhancing its overall functionality! Choose us; choose quality.
