Flutter App Debugging & File Recovery Assistance Needed

I have developed a Flutter application that was previously working, but I am currently facing build and runtime issues. Additionally, I accidentally deleted some important project files and need help recovering them or restoring the project to a stable state.

I am looking for an experienced Flutter developer who can:

• Debug and fix build errors (Android/Gradle/Java issues)
• Resolve protobuf/gRPC-related problems (if applicable)
• Help recover or reconstruct deleted project files
• Ensure the app runs properly on Android
• Review project structure and fix configuration issues
• Guide me on best practices to avoid similar problems in the future

The ideal candidate should have experience with:

• Flutter & Dart (Intermediate to Advanced)
• Android build system (Gradle, SDK, Java configuration)
• gRPC & Protobuf (if relevant)
• Git version control (to help set up backup/versioning properly)
• Debugging complex build errors

Important:

I would also like guidance on:

• Proper project backup strategy
• Using Git for version control
• Safe file management practices
• How to prevent accidental data loss in future

This is both a debugging task and a learning opportunity for me.
