Fix Flutter App & Laravel Website Issues

I need a Flutter developer to fix several issues in our mobile app and website admin panel.

App Issues:
- Address Persistence: The user's address should be saved in local storage and remain after closing the app.
- Video Playback on iOS: Product videos require two taps to start on iOS. This should be fixed to start on the first tap like on Android.

Website Issue:
- Replace the current product editor, which uses an external API, with a simple, free, built-in text editor with no external dependencies.

Requirements:
- Strong experience with Flutter for cross-platform iOS and Android.
- Good knowledge of web development (PHP/Laravel/Node + JS) for replacing the editor.
- Must deliver stable, tested fixes.

When bidding, please include:
- Experience with Flutter bug fixing (portfolio/examples).
- Similar work done on website editors.
- Estimated timeline & budget.
