Firebase Hosting for Flutter Web

Short summary

Technical guide for deploying Flutter web apps on Firebase Hosting, covering setup, routing configuration, and common production pitfalls. Key issue: Flutter's default hash-based routing produces unprofessional URLs requiring PathUrlStrategy and Firebase rewrites. Most deployment failures stem from configuration details like aggressive caching and large builds rather than code defects.

• •Switch from hash-based to path-based routing for clean, professional URLs
• •Configure Firebase rewrites in firebase.json to handle SPA routing
• •Test production builds locally; common issues are caching, build size, and hardcoded configs
