Flutter App Performance and Bug Fixes

I am having some issues with my Flutter app that I need help with. I'm experiencing problems in the following areas:

- Performance: The performance issues haven't been clearly identified as I skipped this part, but an overall performance optimization is required.

- Functionality bugs: I was unable to provide specific examples of these errors, so a general debugging is needed.

The ideal freelancer for this job would be proficient in Flutter and have experience with both performance optimization and debugging mobile apps. I would appreciate if the chosen one could identify and suggest fixes for all undesired behaviors in the app.
